As a rule of thumb, the Atomic Mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
One kilogram = 1000 grams Therefore 42g = 42 divided by 1000 = 0.042kg
One cup of cocoa pebbles typically weighs around 42 grams.
4 g of Helium = 1 mole.So, 56 g of helium = 14 moles
42 ounces = 2.625 pounds (2 5/8 pounds, or 2 pounds and 10 ounces) There are 16 avoirdupois ounces to a pound, so dividing 42/16 = 2.625 Removing the whole pounds leaves 42 - 32 = 10 which is 10/16 or 5/8 of a pound
To find the number of moles of Na in 42 grams, we can use the molar mass of Na, which is approximately 23 grams/mol. First, calculate the number of moles by dividing the given mass by the molar mass: 42 grams / 23 grams/mol = 1.83 moles of Na.
0.5 moles of sodium bicarbonate is equal to 42 grams.
To calculate the number of moles in 42 grams of CO2, we first need to find the molar mass of CO2, which is approximately 44 grams per mole. Then, divide the given mass by the molar mass to find the number of moles. In this case, 42 grams of CO2 is equivalent to 42/44 = 0.955 moles.
To calculate the number of moles in 25 grams of NaCl, divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.44 g/mol. Therefore, 25 grams of NaCl is equivalent to approximately 0.43 moles.
42 grams is 1.48 ounces.
42 kilograms = 42000 grams (1 kilogram is 1000 grams)
42 grams of water is approximately 2.963 tablespoons.
There are 1000 grams in one kilogram. Therefore, 42 kilograms is equal to 42 x 1000 = 42000 grams.
1 kilogram = 1,000 grams 42 kilograms = 42,000 grams
To calculate the amount of AlO produced, you first need to determine the limiting reactant by converting the grams of Al and FeO to moles, then comparing their molar ratios. Once you find the limiting reactant, use stoichiometry to calculate the moles of AlO produced. Finally, convert the moles of AlO to grams. The same steps can be used to find the amount of Fe produced.

That is aluminum hydroxide and as a polyatomic ion hydroxide needs to be in parenthesis. Thus; Al(OH)3 This shows aluminum's 3+ oxidation state and the three matching hydroxides 1- state. 42 grams Al(OH)3 ( 1 mole Al(OH)3/78.004 grams) = 0.538 moles Al(OH)3 As significant figures require; 0.54 moles Al(OH)3
