Question

A) How many grams of H are in 0.45 mol of (C3H5)2S?

B) How many grams of C are in 4.42 g of (C3H5)2S?

C) How many grams of S are in 25.4 g of (C3H5)2S?

Answer 1

A) How many grams of H are in 0.45 mol of (C3H5)2S?

Ans: 1 mole of (C3H5)2S contains 10 moles of H

0.45 mole of (C3H5)2S will contain moles of H

The atomic weight of H is 1 g/mol.

4.5 moles of H corresponds to of H.

B) How many grams of C are in 4.42 g of (C3H5)2S?

The molar mass of

4.42 g of

1 mole of 6 moles of C

0.03877 moles of of C

The atomic mass of C is 12 g/mol.

Mass of C

C) How many grams of S are in 25.4 g of (C3H5)2S?

The molar mass of

25.4 g of

1 mole of 6 moles of C

0.2228 moles of of S

The atomic mass of S is 32 g/mol.

Mass of S
