Question

Wha is the density of 0.50 grams of gaseous carbon stored under 1.5 atm of pressure at a temperature of -20.0 c

A. 0.87 g/L
B. 0.58 g/L
C. 8.0 g/L
D. 1.2 g/L

Answer 1

From Ideal Gas Equation
PV = nRT
V = nRT/ P
= (0.5/12)*0.82*-20/1.5
=0.042*0.82*-20/1.5

Volume = 0.46

Density = 0.5/0.46
= 1.08 gm/cc
