Calculate the energy change when 50.0 g of ice melts (H fusion = 334 kJ/mol). Molar mass for water 18 g/mol

Question

in simple steps

Answer 1

To calculate the energy change when 50.0 g of ice melts, we can use the equation:

Energy Change = Mass of Substance x Heat of Fusion.

1. Convert the mass of ice from grams to mols:
50.0 g / 18 g/mol = 2.77 mol

2. Calculate the energy change using the heat of fusion:
Energy Change = 2.77 mol x 334 kJ/mol = 925.18 kJ

Therefore, the energy change when 50.0 g of ice melts is 925.18 kJ.
