Question

Molar volume of 17 g ammonia is

• A. 22.4 L
• B. 224 L
• C. 2.24 L
• D. .224 L

Answer 1

Answer:

A. 22.4 L

• The molar mass of ammonia is 17 g/mol (14 for Nitrogen + 3 for Hydrogen).

• 17 g of ammonia corresponds to 1 mole of ammonia.

• At STP, 1 mole of any gas occupies 22.4 liters volume.

Therefore, 17 g of ammonia gas occupies 22.4 liters at STP.
