So to solve for this, since there's no change in temperature within the given problem, so our heat will only be required for the phase change.
00:14
So the melting of ice, so that means from solid to liquid.
00:19
So the heat required for phase change, q will be equivalent to the number of moles multiplied by d, heat up, fusion of.
00:30
The substance which is in this case or the ice.
00:33
This is number of moles multiplied by the heat of fission.
00:37
So we have the mass of the ice which is 75 grams, but we need the number of moles.
00:46
So we're going to need the molar mass and ice basically is just water.
00:51
So if we have 75 grams of ice, that's 75 grams of water...
