Steam at `100^@C` is allowed to pass into a vessel containing `10g` of ice and 100 g of water at `0^@C` until all the ice is melted and the temperature is raised to `50^@C`. Neglecting water equivalent of the vessel and the loss due to radiation etc. Calculate how much steam is condensed.

Explanation

If `m` mass of steam,
`10xx80+(10+100)xx1xx(5-0)=mxx540+mxx1xx(100-5)`
`1350=635m`
`m=(1350)/(635)=2.12g`
