This problem is confusing me... I'm not sure where to start exactly

A sample of ice weighing 16.84 g, initially at -47.3°C, is heated to 140.0°C at a constant pressure of 1.00 atm. Calculate q, w, E, H, and S for this process. The molar heat capacities (Cp) for solid, liquid, and gaseous water (37.5 J K-1 mol-1, 75.3 J K-1 mol-1, and 36.4 J K-1 mol-1) respectively-are assumed to be temperature independent. The enthalpies of fusion and vaporization are 6.01 kJ/mol and 40.7 kJ/mol, respectively. Assume ideal gas behavior.


What am i supposed to do with the grams? Is that just the moles of H2O?

Convert grams to moles.
