Weight of CO2CO_{2}in a 10 L cylinder at 5 atm and 270C27^{0}Cis

A

200 g

B

224 g

C

44g

D

89.3g89.3g

Answer

89.3g89.3g

Explanation

Solution

: PV=nRT=mMRTPV = nRT = \frac{m}{M}RT

P = 5 atm, V = 10 L, T = 300 k,

R=0.0821Latmk−1mol−1R = 0.0821Latmk^{- 1}mol^{- 1}

m=PVMRT=5×10×440.0821×300=89.3gm = \frac{PVM}{RT} = \frac{5 \times 10 \times 44}{0.0821 \times 300} = 89.3g
