A 5.00L steel cylinder is filled with water vapor at 650mmHg and 100C. Calculate the density of the gas.

1 answer

Use a modified gas law of PV = nRT modified to be
PM = dRT. P is pressure in atm, M is molar mass H2O, d is density (units of g/L), R is 0.08206 and T is in kelvin. Solve for density.
