Here, the energy released by the condensation of vapour is not sufficient to melt the whole ice. So, the amount of energy released by the water vapour, when it condensed and comes to 00C is,

E=(mvapour)(Lvapour)+(mvapour)(Svapour)×100⇒E=10×540+10×1×100⇒E=6400 cal

So, let m mass of the ice is m'. Therefore,

m'Lice=6400 ⇒m'=640080⇒m'=80 gm
Therefore, the total amount of water in the capillary tube is,

m0=500+80+10 ⇒m0=590 gm
