A home owner uses ` 4 . 00 xx 10^(3) m^(3)` of methane `(CH_(4))` gas, (assume `CH_(4)` is an ideal gas ) in a year to heat his home. Under the pressure of 1.0 atm and 300 K , mass of gas used is `x xx 10^(5)` g . The value of x is ______ (Nearest i nteger)
(Given R = `0 . 083 ` L atm ` K^(-) mol ^(-)` )

Text Solution

Verified by Experts

The correct Answer is:
26
PV - nRT
Mass = `(1xx4xx10^(6))/(0.083 xx 300) xx16 = 25.7 xx 10^(5)g`
`approx 26 xx 10^(5)` g .
