This worked example problem shows you how to convert moles to grams.

**Problem**

Determine the mass in grams of 3.60 mol of H_{2}SO_{4}.

**Solution**

First, look up the atomic masses for hydrogen, sulfur, and oxygen from the Periodic Table. The atomic mass is 1.008 for H; 32.06 for S; 16.00 for O. The formula mass of H_{2}SO_{4} is:

2(1.008) + 32.06 + 4(16.00) = 98.08

Thus, one mole of H_{2}SO_{4} weights 98.08 grams. This relation provides a conversion factor to go from grams to moles. Using the factor 98.08 g / 1 mol:

grams H_{2}SO_{4} = 3.60 mol x 98.08 g / 1 mol = 353 g H_{2}SO_{4}

**Answer**

353 g H_{2}SO_{4}
