Potassium Sulfide - K2S
2 Potassium
1 Sulfur
Potassium = 39 grams per mole
Sulfur = 32 grams per mole
Add up the total mass - 2 K's and 1 S:
2(39) + 1(32) = 110 grams/mole
Now just make sure the units cancel so that you can multiply or divide out the mole unit
3.3 mole K2S x 110 grams K2S/mole
mole unit cancels and you're left with 363 grams K2S

How many moles of potassium iodide are there in 50 grams?
For this you need the atomic (molecular) mass of KCl. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. KCl= 74.6 grams50.0 grams KCl / (74.6 grams) = .670 moles KCl
How many grams of potassium bromite (KBrO2) are there in 0.280 moles?
To calculate the grams of potassium bromite in 0.280 moles, you would multiply the number of moles by the molar mass of KBrO2, which is 119 g/mol. Therefore, 0.280 moles of KBrO2 would be 0.280 moles * 119 g/mol = 33.32 grams.
How many grams are in 3.3 moles of potassium sulfide K2S?
To find the number of grams in 3.3 moles of potassium sulfide (K2S), you need to calculate the molar mass of K2S, which is 110.26 g/mol. Then, you can multiply the molar mass by the number of moles to get the grams. In this case, 3.3 moles x 110.26 g/mol = 363.858 g.
What is the mass in grams of 2x1012 atoms of potassium?
To calculate the mass of 2x10^12 atoms of potassium, you first need to find the molar mass of potassium (39.10 g/mol). Then, divide the number of atoms by Avogadro's number to get the moles of potassium. Finally, multiply the moles by the molar mass to find the mass in grams, which in this case would be 0.01566 grams.
