Ammonia is composed of one nitrogen atom and three hydrogen atoms. The molar mass of ammonia is 17.03 g/mol, with 3.04 g/mol from the hydrogen atoms. To find the grams of hydrogen in 10.0 g of ammonia, we need to calculate the proportion of hydrogen in the compound. This comes out to 3.04 g H x (10.0 g NH3 / 17.03 g NH3) = 1.79 g H.

What is the mass percentage of hydrogen in ammonia?
The molar mass of ammonia (NH3) is 17.03 g/mol. Hydrogen's molar mass is 1.01 g/mol. The mass of hydrogen in ammonia is 3.03 g (3*1.01). To find the mass percentage of hydrogen in ammonia: (3.03 g / 17.03 g) * 100% ≈ 17.8%.
Nitrogen and hyrogen form ammonia by the reaction N2 plus 3H2 to 2NH3. If 56 grams of nitrogen and 85 grams of hydrogen react to form 62 grams of ammonia. What is the percent yield?
To find the percent yield, first calculate the theoretical yield of ammonia based on the given amounts of nitrogen and hydrogen. Then compare the actual yield (62g) with the theoretical yield to calculate the percent yield using the formula: (actual yield/theoretical yield) x 100%. The percent yield would be the actual mass of ammonia produced (62g) divided by the theoretical yield of ammonia.
What is the molarity of household ammonia?
My understanding is that household ammonia is 0.85% ammonia (NH3). This equates to 0.85 grams per 100 grams (mililiters) of water or 8.5 grams per liter of water. The molar mass of ammonia is about 17. So 8.5 grams divided by 17 grams per mole equals 0.5, which is the molarity of household ammonia.
Which compound has a higher percent by mass of hydrogen- h2o or h2o2?
lets see. H20 you have 2.016 grams of hydrogen here to 16.0 grams oxygen 2.016/16.0 X 100 = 12.6% hydrogen by mass H2O2 you have the same 2.016 grams hydrogen here, but you have 32.0 grams oxygen in this molecule 2.016/32.0 X 100 = 6.3% so H2O has the higher percent by mass of hydrogen
How many molecules of hydrogen chloride would there be in 100 grams of this gas?
To determine the number of molecules in 100 grams of hydrogen chloride gas, you need to first calculate the number of moles present using its molar mass. The molar mass of HCl is about 36.5 g/mol. Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
How much of each element is there if you have a 100 gram compound and 80 percent is carbon and 20 percent is hydrogen?
For carbon 0.80 x 100 = 80 grams of carbon; and for hydrogen 0.20 x 100 = 20 grams of hydrogen
What is the mass percentage of hydrogen in ammonia?
The molar mass of ammonia (NH3) is 17.03 g/mol. Hydrogen's molar mass is 1.01 g/mol. The mass of hydrogen in ammonia is 3.03 g (3*1.01). To find the mass percentage of hydrogen in ammonia: (3.03 g / 17.03 g) * 100% ≈ 17.8%.
100 grams of ammonia equals how many moles?
For this you need the atomic (molecular) mass of NH3. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. NH3=16.0 grams100 grams NH3 / (16.0 grams) = 6.25 moles NH3

Then compare the actual yield (62g) with the theoretical yield to calculate the percent yield using the formula: (actual yield/theoretical yield) x 100%. The percent yield would be the actual mass of ammonia produced (62g) divided by the theoretical yield of ammonia.
Do onions contain ammonia?
Onions do not naturally contain ammonia. They contain sulfur compounds that can produce a pungent smell and flavor when the onion is chopped or crushed, but this is different from the smell of ammonia.
100 grams has how many oz in it?
100 grams = 3.5 ounces.
What is the molarity of household ammonia?
My understanding is that household ammonia is 0.85% ammonia (NH3). This equates to 0.85 grams per 100 grams (mililiters) of water or 8.5 grams per liter of water. The molar mass of ammonia is about 17. So 8.5 grams divided by 17 grams per mole equals 0.5, which is the molarity of household ammonia.
How many grams of hydrogen must be added to 800 grams of oxygen to produce 900 grams of water?
For the reaction 2H₂ + O₂ → 2H₂O, we know that the molar ratio of H₂ to O₂ is 2:1. To produce 900 grams of water, we need 450 grams of hydrogen (900g / 2). Therefore, we need to add 450 grams of hydrogen to 800 grams of oxygen to produce 900 grams of water.
How many oz is 100 grams?
100 grams is 3.527 ounces.
How many kilograms is 100 grams?
.1 Kg = 100 grams
Water its 11.2 percent by mass hydrogen How many kilograms of water would contain 5.0 grams of hydrogen?
To find the mass of water containing 5.0 grams of hydrogen, we need to set up a proportion using the mass percentage of hydrogen in water. Since water is 11.2% hydrogen by mass, we can calculate the mass of water using the formula: (5.0 grams of hydrogen) / (11.2 grams of hydrogen per 100 grams of water) = x grams of water. Converting grams to kilograms, the mass of water containing 5.0 grams of hydrogen would be 5.0 g / 11.2% = 44.64 g. This figure converted to kilograms is 0.04464 kg.
Which compound has a higher percent by mass of hydrogen- h2o or h2o2?
lets see. H20 you have 2.016 grams of hydrogen here to 16.0 grams oxygen 2.016/16.0 X 100 = 12.6% hydrogen by mass H2O2 you have the same 2.016 grams hydrogen here, but you have 32.0 grams oxygen in this molecule 2.016/32.0 X 100 = 6.3% so H2O has the higher percent by mass of hydrogen
