Question

A tanker truck carrying 3.02×103 kg of concentrated sulfuric acid solution tips over and spills its load. The sulfuric acid solution is 95.0% H2SO4 by mass and has a density of 1.84 g/mL.

Sodium carbonate (Na2CO3) is used to neutralize the sulfuric acid spill. How many kilograms of sodium carbonate must be added to neutralize 3.02×103 kg of sulfuric acid solution?

Na2CO3 + H2SO4 → Na2SO4 + CO2 + H2O   [balanced as written]

(3.02×10^3 kg H2SO4) × (0.950) / (98.0791 g H2SO4/mol) ×

(1 mol Na2CO3 / 1 mol H2SO4) × (105.9884 g Na2CO3/mol) =

3.10×10^3 kg Na2CO3
