A vessel of volume V=7.5 litres contains a mixture of ideal gases at temperature T=300K. There are n_(1)=0.1 mole of oxygen (M_(1)=32), n_(2)=0.2 mole of nitorgen (M_(2)=28) and n_(3)=0.3 mole of carbon dioxide (M_(3)=44). Assuming the gases to be ideal, find (a) the pressure of the mixture, (b) the man molar mass M of the mixture.
