60 g of gaseous C 2 H 6 are mixed with 28 g of carbon monoxide. The pressure of the resulting gaseous mixture is 3 atm. The partial pressure in atm. of C 2 H 6 in the mixture is

Step-by-step solution

Moles of C 2 H 6 = 60 g 32 g / m o l = 2 m o l moles of C O = 28 g 28 g/mol = 1 mol Mole fraction C 2 H 6 = 2 2 + 1 = 2 3 Partial pressure of C 2 H 6 = P t o t a l × Mole fraction of C 2 H 6 = 3 atm × 2 3 = 2 atm .
