## Homework Statement

1 625g iron block is heared to 352 C is placed in an insulate container (of negligible heat capacity) containing 40g of water at 15 C. what is the equilibrium temp of this system? if your answer is 100 C, determine the amount of water that has vaporized.

## Homework Equations

Q(block)=mc(T-Tblock) = .625(560)(T-352)

Q(water)=.040(4186)(T-15)

## The Attempt at a Solution

set Q(block)=Q(water) i got T=242.95.. how was i suppose to get 100 C?

how do i solve how many grams of water have evaporated.

im so lost on this probelm, any help would be appreciated.
