FIND THE ISSUE IN THE CALCULATION OF THE PRESSURE OF THE STEAM

A $1\mathrm{.}1\mathrm{.}820-m^3$ rigid tank contains steam at $220C$ One$-$third of the volume is in the liquid phase and the rest is in the

vapor form. The properties of steam at $220C$ are given as follows: $v_f=0\mathrm{.}001190\frac{m^3}{k}g$ and $v_g=0\mathrm{.}08609\frac{m^3}{k}g$

What is the pusssume of the stean?

Volume of liquid:

$V_L=(\frac{1}{3})(1\mathrm{.}820m^3)$

$V_L=0\mathrm{.}607m^3$

Volure of blean:

$V_S=(\frac{2}{3})(1\mathrm{.}820m^3)$

$V_S=1\mathrm{.}213m^3$

Mass of $L$ iquid $($using foumla$)$:
