Molar volume at STP is $22.4 L/mol$ . Copper reacts with dilute nitric acid as $3 Cu + 8 HNO X_{3} 3 Cu (NO X_{3}) X_{2} + 2 NO + 4 H X_{2} O$ . The volume of $NO$ at STP obtained from $0.3$ mol of $Cu$ is:

Mole ratio

Cu : NO = 3 : 2

, so

n (NO) = 0.3 \times 2/3 = 0.2

mol. Volume

= 0.2 \times 22.4 = 4.48 L
