How many grams are there in 3.3 moles of potassium sulfide?

Answer 1

The Atomic Mass of Potassium is 39 and that of Sulfur 32. The formula for Potassium Sulfide is K2S therefore the molecular weight of Potassium Sulfide is (39 * 2) + 32 = 110. Therefore one mole of Potassium Sulfide weighs 110 grams. Therefore 3.3 moles of Potassium Sulfide weigh 110 * 3.3 = 363 grams.

Answer 2

This problem requires potassium's atomic mass. Take the number of moles multiply it by the atomic mass. Going from grams to moles, you would divide instead.

3.00 mole K × (39.1 grams) = 117.3 grams K

Answer 3

This problem requires potassium's atomic mass. Take the number of moles multiply it by the atomic mass. Going from grams to moles, you would divide instead.

3.00 mole K

Answer 4

There are 0.246 moles in 10g of potassium.

Answer 5

1 mole Na = 22.990g Na

10g Na = 1mol Na/22.990g Na = 0.4 mole Na

Answer 6

3.3 moles of potassium sulfide is equal to 363,86 g.

Answer 7

300 g of potassium is equal to 7,67 moles.
