Assessment: WAEC SSCE - Chemistry - 2010 (Objective) Subject: Chemistry

Question 1 Report

What is the volume occupied by 2 moles of ammonia at s.t.p?
Answer Details
The volume occupied by 1 mole of any ideal gas at standard temperature and pressure (STP) is 22.4 dm3 or 22.4 L. STP is defined as a temperature of 273 K (0 °C) and a pressure of 1 atm (101.325 kPa). Therefore, the volume occupied by 2 moles of ammonia at STP would be: V = 2 × 22.4 dm3 = 44.8 dm3 So the correct option is (a) 44.8 dm-3.
