Question

2.5 L of dry Nitrogen gas is collected at a temperature of 27oC and a pressure of 740mm of Hg.

Find the volume of gas at S.T.P.
​

Answer 1

Answer:

V = 2.21

Explanation:

Data

Volume of N2 gas Colleceted = V1 = 2.5L

Tempertaure = T1 = 27°C + 273 = 300k

Pressure = 740mmHg

find

Volume = V 2= ?

T2= 0°C+ 273 = 273k

P2 =760mmHg

Solution

P1V1/T1 = P2V2/T2

V2 = P1V1T2/T1P2

V2 = 740 * 2.5 * 273 /760 * 300

V2 = 2.21L
