42.7 gram sample of potassium nitrate contains how many grams of potassium?
Potassium nitrate has a molar mass of 101.1 g/mol, with one potassium atom accounting for 39.1 g/mol. Using a simple stoichiometric calculation, it can be determined that a 42.7 g sample of potassium nitrate contains approximately 16.64 grams of potassium.
How many grams of crystals will b formed if a saturdayed potassium nitrate solution is cooled from 60 to 30?
The amount of crystals formed will depend on how much potassium nitrate was dissolved in the solution to begin with. As the solution cools from 60°C to 30°C, potassium nitrate will begin to crystallize out of the solution. The exact amount of crystals can be determined by calculating the solubility of potassium nitrate at 30°C and comparing it to the initial concentration in the solution.
How do you prepare one normal solution of potassium nitrate?
To prepare one normal solution of potassium nitrate, you would dissolve 101.1 grams of potassium nitrate in enough water to make 1 liter of solution. This solution will have a concentration of 1 mole per liter, which is considered a normal solution. Make sure to use a balance to accurately measure the mass of potassium nitrate and a volumetric flask to ensure a final volume of 1 liter.
How many molecules are present in 691 grams of potassium carbonate?
30.115*10^23 molecules
What is the maximum mass of potassium chloride that will dissolve in 100 grams of water?
The maximum mass of potassium chloride that will dissolve in 100 grams of water at room temperature (20°C) is approximately 37.2 grams.

How much potassium nitrate will dissolve in 50 grams of water at 50C?
Approximately 246 grams of potassium nitrate will dissolve in 50 grams of water at 50°C.
How many grams of potassium iodide will produce 750 grams of silver iodide when there is an excess of silver nitrate?
530,3 g potassium iodide are needed.
What mass of potassium nitrate would be needed to produce a saturated solution of potassium nitrate in 50 grams of water at 313K?
At 313K, the solubility of potassium nitrate in water is approximately 62g/100g of water. To form a saturated solution in 50g of water, you would need roughly 31g of potassium nitrate.
How many molecules are there in 65 g of silver nitrate (AgNO3)?
Well, because you have 65g of AgNO3, you have .3826 moles of silver nitrate. This is found by dividing the number of grams you have by the molar mass of silver nitrate (169.9g/mol). Once you know how many moles there are you can then multiply by Avogodro's number (6.022x1023) to obtain the number of molecules. In this case it is 2.304x1023 molecules.
What is 1 mole of ammonium nitrate?
One mole of ammonium nitrate is equal to its molar mass, which is approximately 80.04 grams. This quantity represents Avogadro's number of individual ammonium nitrate molecules.
How many grams of potassium nitrate can we dissolve in ml of water at A degrees Celsius?
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
How many molecules are there in 65 g of silver nitrate?
To determine the number of molecules in 65 g of silver nitrate, you first need to calculate the number of moles of silver nitrate using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert the moles of silver nitrate into molecules.
