Based on the number of moles of H_2SO_4, determine the number of moles of Na_2CO_3 needed for the neutralization reaction.

Sodium carbonate ( Na_2CO_3) is used to neutralize the sulfuric acid spill. How many kilograms of sodium carbonate must be added to neutralize 4.03×103 kg of sulfuric acid solution?

3.90 * 10^4 = H_2SO_4 mol

Mole to mole ratio is 1:1.
