Question

Calculate the volume occupied by 8.8 g of CO2 at 31.1°C and 1 bar pressure.

R = 0.083 bar L K–1 mol–1.

Solution 1

It is known that,

`pV = m/M  RT`

`=> V  = (mRT)/(Mp)`

Here

m = 8.8 g

R = 0.083 bar LK–1 mol–1

T = 31.1°C = 304.1 K

M = 44 g

p = 1 bar

Thus volume (V) = `(8.8 xx 0.083 xx 304.1)/(44xx1)`

= 5.04806 L

= 5.05 L

Hence, the volume occupied is 5.05 L.

Solution 2

No of Mole of `CO_2 (c)` = `("Mass of " CO_2)/"Molar Mass"`

`= (8.8 g)/(44g mol^(-1)) = 0.2 mol`

Pressure of `CO_2 (P) = 1 "bar"`

`R = 0.083 "bar " LK^(-1) mol^(-1)`

Temperature (T) = 273 + 31.1

= 304.1 K

Since from gas equation  PV = nRT

V = nRT/P = `(0.2 xx 0.083 xx 304.1)/ (1 "bar")`

= 5.048 L

  Is there an error in this question or solution?
