31.3 L of concentrated nitric acid (8.50 mol L-1) was spilled on a road. Sodium carbonate solid was spread on the acid to react as in the equation:
CO32-(aq) + 2H+ → CO2(g) + H2O
How many grams of sodium carbonate are needed to neutralise the acid?
If 1litre= 8.50mol
31.3×8.50= 266.05moles
Mole ratio= 1:2
Moles of sodium carbonate= (1/3)×266.05
= 88.68moles
Mass= 106× 88.68= 9400.43g
