The formula mass of potassium sulfide, K2S is 2(39.1)+32.1=110.3

1 mole of potassium sulfide has a mass of 110.3g

Mass of 3.3mol of K2S = 3.3 x 110.3 = 364g

How many moles in potassium bicarbonate?

You did not describe the amount of potassium bicarbonate amount in grams in your question. But if you are about 1 gram of potassium bicarbonate it will be 0.0099 moles in one gram of potassium bicarbonate. 0.0199 moles in 2 grams of potassium bicarbonate.


How many grams of potassium permanganate are in 2.20 moles?

To calculate the grams of potassium permanganate in 2.20 moles, you would need to know the molar mass of potassium permanganate. The molar mass of potassium permanganate (KMnO4) is about 158.034 g/mol. So, 2.20 moles of KMnO4 is equal to 2.20 moles x 158.034 g/mol = 347.67 grams of potassium permanganate.


How many moles of potassium are contained in 449g of potassium?

To find the number of moles, you first need to calculate the molar mass of potassium (39.10 g/mol). Then, divide the given mass (449g) by the molar mass to get the number of moles. In this case, 449g of potassium would contain approximately 11.5 moles.


How many moles are contained in 245g of potassium bromide?

To find the number of moles in 245g of potassium bromide, first calculate the molar mass of KBr by adding the atomic masses of potassium (39.10 g/mol) and bromine (79.90 g/mol). The molar mass of KBr is 119.00 g/mol. Then, divide the given mass by the molar mass: 245g / 119.00 g/mol = 2.06 moles of potassium bromide.
