JAMB Physics 2012 Objective — Question 21

Question 21 of 50 from the Joint Admissions and Matriculation Board (JAMB) Physics 2012 Objective paper, with the correct answer and a full explanation.

2000cm³ of a gas is collected at 27°C and 700mmHg. What is the volume of the gas at standard temperature and pressure?

A. 1896.5cm³
B. 1767.3cm³
C. 1676.3cm³Correct
D. 1456.5cm³

Explanation

Using P1V1/T1 = P2V2/T2: V2 = (P1V1T2)/(T1P2) = (700×2000×273)/(300×760) ≈ 1676.3cm³.
