could you please help me with numbers 2 and 3?

2) The density of liquid argon at its normal boiling point of 185.85C is 1.40g/cm3. a) What is the volume (in liters) of 12.5kg of liquid argon at this temperature? b) What is the mass of 1.5 liter of liquid argon at this temperature? c) What would be the vapor pressure of the argon gas above the liquid? [8.93 L] [2.1103g] [1 atm] 3) Suppose one has 10.0g of water is contained in a rigid 250L container at 25C and then heated to the water to 125C where all water is turned to vapor. What would be the pressure of the resulting water vapor formed in units of atm. Assume vapor behaves as an ideal gas. [0.073 atm]
