Question

How much heat is needed to melt 45.00 g of ice at 0°C if the latent heat of fusion of water is 333.7 J/g? 288.7 J 378.7 J 14,220 J 15,020 J

Answer 1

15 020 J

Step-by-step explanation:

Answer 2

15 020 J

Step-by-step explanation:

The formula for the heat (q) is

q = mΔH_fus

Data:

m = 45.00 g

ΔH_fus = 333.7 J·g⁻¹

Calculation:

q = 45.00 g × (333.7 J/1 g)

= 15 020 J
