The volume of 2.5 moles of oxygen at s.t.p is [Molar volume of a gas at s.t.p = 22.4 dm3]

Assessment: JAMB UTME - Chemistry - 2006 Subject: Chemistry

Question 1 Report

The volume of 2.5 moles of oxygen at s.t.p is

[Molar volume of a gas at s.t.p = 22.4 dm3]

Answer Details
The question is asking for the volume of 2.5 moles of oxygen at standard temperature and pressure (s.t.p), given that the molar volume of a gas at s.t.p is 22.4 dm^3. To solve this problem, we can use the following formula: Volume = (number of moles) x (molar volume at s.t.p) Substituting the given values, we get: Volume = 2.5 mol x 22.4 dm^3/mol Volume = 56.0 dm^3 Therefore, the volume of 2.5 moles of oxygen at s.t.p is 56.0 dm^3. So, the answer is the last option: 56.0 dm^3.
