6 litres of ${\text{H}}_{\text{2}}\text{O}$  is placed in an evacuated room of volume $\text{827 litre}$  and temperature of  

$\text{3}00\text{ K}.$ If vapour pressure of liquid water is $\text{22}.\text{8 mm of Hg at 3}00\text{ K}$  and its density is  

$\text{1 g}/{\text{cm}}^{\text{3}}.$Then: 
[Given $\text{R}=0.0\text{821 L}–\text{atm}/\text{mole}–\text{K},$  assuming volume of liquid water to be constant]
