7) Sulfur trioxide reacts with water (violently) to produce sulfuric acid in the reaction SO_(3)+H_(2)Oarrow H_(2)SO_(4) Calc the number of liters of sulfur trioxide needed to produce 32.1g of sulfuric acid.

## Step 1The first step in this problem is to convert the mass of sulfuric acid (H2SO4) into moles. This is done by using the molar mass of H2SO4, which is 98.079 g/mol. The formula for this conversion is:### ## Step 2Next, we use the stoichiometry of the reaction to find the number of moles of sulfur trioxide (SO3) needed. The stoichiometry of the reaction is 1:1, which means that one mole of SO3 reacts with one mole of H2SO4.## Step 3Finally, we convert the number of moles of SO3 into liters using the ideal gas law, which states that one mole of any gas at standard temperature and pressure (STP) occupies 22.4 liters. The formula for this conversion is:###
