"if the heat of fusion for water is 80. cal/g, how many calories are needed to melt 45.0 g of ice at 0 ? c? "

Energy released from changing the phase of a substance from the liquid phase to the solid phase at a constant temperature can be calculated by using the latent heat of fusion. Calculation are as follows:

 Energy = 80 cal / g (45.0 g)

Energy = 3600 cal

did anyone actually do this? like if anyone has submitted this i rly need .

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.
