Explanation:
Detailed explanation-1: -Answer: 1.7 g of ammonia contains 0.1 moles of ammonia and occupies volume equal to 2.271 dm3.
Detailed explanation-2: -Molar mass of NH3 is 17g. So the volume of 17g of NH3 i.e 1 mole NH3 at N.T.P. will be 22.4L.
Detailed explanation-3: -∴ Volume occupied by 20 moles of NH3 at STP = 22.4 × 20 = 448 L.
Detailed explanation-4: -4.4 g of a gas at STP occupies a volume of 2.24 L.
