Question

Find the number of mole of a gas if the temperature pressure and
volume of that gas are O'C, 760 mm Hg and 1000 cc respectively
[R=8.3144 JK' mol']

​

Answer 1

Answer:

0.045 moles

Explanation:

given data:

T= 0°C = 273K

P= 760mm of Hg = 1atm

V = 1000cc = 1L

using R as 0.0821LatmK-1mol-1 instead of 8.314 JK-1mol-1 because of easier calculation

both will give same answer if u use 8.314 and convert all value to si units

PV=nRT

(1)(1)=n(0.0821)(273)

n=1/22.4

n=0.045 moles

hope it helps u
