Question

A vessel of volume 4 litres contains a mixture of 8 g of oxygen, 14 g of nitrogen and 22 g of carbon dioxide at 27°C. The pressure exerted by the mixture is (A) 5.79 × 105 N m-2 (B) 6.79 × 105 N m-2 (C) 9.34 × 109 N m-2 (D) 9.34 × 105 N m-2

The pressure exerted by the mixture, P = P1 + P2 + P3 = ((nRT/V))O2+ ((nRT/V))N2 + ((nRT/V))CO2 = (nO2+nN2+nCO2) (RT/V) = (((8/16)+(14/28)+(22/44))(8.31)×300/4×10-3) = 9.34 Ã 105 N m-2

Q. A vessel of volume 4 litres contains a mixture of 8 g of oxygen, 14 g of nitrogen and 22 g of carbon dioxide at $2 7^{\circ} C$ . The pressure exerted by the mixture is

$5.79 \times 1 0^{5} N m^{- 2}$

$6.79 \times 1 0^{5} N m^{- 2}$

$9.34 \times 1 0^{9} N m^{- 2}$

$9.34 \times 1 0^{5} N m^{- 2}$

Q. A vessel of volume 4 litres contains a mixture of 8 g of oxygen, 14 g of nitrogen and 22 g of carbon dioxide at 27∘C. The pressure exerted by the mixture is

5.79×105Nm−2

6.79×105Nm−2

9.34×109Nm−2

9.34×105Nm−2

The pressure exerted by the mixture, P=P1​+P2​+P3​ =(VnRT​)O2​​+(VnRT​)N2​​+(VnRT​)CO2​​ =(nO2​​+nN2​​+nCO2​​)VRT​=4×10−3(168​+2814​+4422​)(8.31)×300​ =9.34×105Nm−2
