A home owner uses 4 . 00 × 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 × 10 5 g . The value of x is ______. (Nearest integer) (Given R = 0 . 083 L atm K - 1 mol - 1 )

Correct answer

0

Step-by-step solution

n CH 4 = PV RT = 1 × 4 × 10 3 × 1000 0 . 083 × 300 Weight of CH 4 = 40 × 16 × 10 5 0 . 083 × 300 gm = 25 . 7 × 10 5   gm
