Question

Calculate the volume occupied by 8.8g of carbon dioxide at 31.1°c and 1 bar pressure

Answer 1

Weight of  (w) = 8.8 g

Pressure (P) = 1 bar

Temperature = 31.1°C = (273 K + 31.1) = 304.1 K

R =

To find:

Volume (v) = ?

Formula to be used:

Calculation:

Molecular weight of  = 1 (Atomic weight of carbon) + 2 (Atomic weight of oxygen)

Molecular weight of  = 1 (12) + 2(16)

Molecular weight of  = 12 + 32

Molecular weight of  = 44

We know that as per gas equation:

Substituting the given values in the formula gives

1 × V =

1 × V = 0.2 × 0.083 × 304.1

V =

V = 5.04806 = 5.05

Conclusion:

The volume occupied by 8.8 g of  at 31.1°C and 1 bar pressure is calculated as 5.05 L.
