Nitric acid, HN * O_{3} * (aq) can be neutralized by calcium hydroxide , Ca(OH) 2 (aq); Ca(OH) 2 (aq)+2HNO 3 (aq) Ca(NO 3 ) 2 (aq)+2H 2 O(l) of nitric acid is presenthow much mass of calcium hydroxide is needed to neutralize completely the nitric acid?

Agas is inside a cylinder fitted with a piston. the gas and its surroundings are both at 20 ∘c and the gas is compressed as the piston moves and decreases the cylinder volume. the compression takes place slowly enough to allow the gas temperature to stay at 20 ∘c and the work done on the gas by the compression is 2.4 × 103 j.
