The simple (and almost correct) answer is W = (Tend - Tstart) cp m = 50 X 2.51 X 50 = 6275 J In reality the constant cp isn't really a constant. cp(300 K) is closer to 2.2 JK-1g-1 than 2.51, which gives you an integral over the temperature shift, and a value that is slightly lower htan 6275 J.

How do you calculate the total heat required in kcal to take 70 grams of ice at -29.0 Celsius and convert it to steam at 106 Celsius?
heat energy required to raise the temperature of ice by 29 celsius =specific heat capacity of ice * temperature change *mass of ice + to change 1kg of ice at 0 celsius to water at 0 celsius =specific latent of fusion of ice*mass of water + heat energy required to raise the temperature of water by 106 celsius =specific heat capacity of water * temperature change *mass of ice + to change 1kg of water at 106 celsius to steam at 106 celsius =specific latent of fusion of ice*mass of steam

Does methanol lower the freezing point?
Methanol will freeze at negative 143 (Fahrenheit)/ negative 97 (Celsius). If it is added to water (freezing point of 32*F/0*C) then it will make the water freeze at a lower temperature. So yes, methanol will lower the freezing point of any liquid that freezes at a higher temperature than methanol. But methanol cannot lower the freezing point of any liquid that will still be liquid at -143*F/-97*C.
What is the state of methanol at 25 degrees celsius?
