Stoichiometry can be used to answer this question. Stoichiometry is defined as the relationship of quantities of substances taking part in a reaction that form a compound. Stoichiometry problems can be solved using a series of conversion factors. 

In order to convert from the given 18 moles of H2SO4 to grams of H2SO4, the molar mass (grams/ mole) of H2SO is needed. 

The molar mass of a compound can be determined by finding the sum of all the atomic masses of each atom within the compound. 

Therefore, the molar mass of H2SO4 = 

2H = 2.0 g/mol

S = 32.1 g/ mol

4O = 64.0 g/mol

2.0 + 32.1 + 64.0 = 98.1 g/mol

We are given 18 moles of H2SO4, so this will be our starting point within the problem. 

18 mole H2SO4 x (98.1g/1 mole H2SO4) = 1765.8 grams
