Asked by Jack
A student in a lab heats up 50 g of water using a Bunsen burner and an insulated cup to ensure no heat loss to surroundings. The water is initially at 25 °C and is heated until boiling at 100 °C. How much heat is transferred to the water in the insulated cup in the previous question? The specific heat capacity of water is 4.184 J/K/mol.
My answer was 1.7 but it's wrong. Can someone please help? Thanks

I don't know what the previous question is but for this one, you have
50 g x 4.184 J/g*K x (100-25) = 15,689 J which I would round to 1.6 kJ. Watch the significant figures
Note the Cp for H2O is 4.184 J/g and not J/mol
50 g x 4.184 J/g*K x (100-25) = 15,689 J which I would round to 1.6 kJ. Watch the significant figures
