A gaseous mixture of three gases A, B and C has a pressure of 10 atm. The total number fo moles of all the gases is 10. If the partial pressures ofA and B are 3.0 and 1.0 atm respectively and if C has a molecular mass of 2.0, then calculate the weight of C in g present in the mixture.

A gaseous mixture of three gases A, B and C has a pressure of 10 atm.

1.	A gaseous mixture of three gases A, B and C has a pressure of 10 atm. The total number fo moles of all the gases is 10. If the partial pressures ofA and B are 3.0 and 1.0 atm respectively and if C has a molecular mass of 2.0, then calculate the weight of C in g present in the mixture.
