A freely moving impenetrable, thin and weightless piston divides a cylindrical vessel with a volume of V = 100 l into two parts. A certain amount of water is introduced into one part of the vessel, and a certain amount of gas into the other. The temperature in the vessel is maintained at T = 373 K. What pressure will be established in the vessel if: a) m1 = 74 g of water, m2 = 10 g of hydrogen are introduced into it; b) m1=74 g of water, m2=74 g of carbon dioxide; c) m1=36 g of water, m2=2.8 g of nitrogen. Molar masses: water v1=18 g/mol, hydrogen v2=2 g/mol, carbon dioxide v(CO2)=44 g/mol, nitrogen v(N2)=28 g/mol.
