Question

If you have 7.3g of solid calcium and it takes 62.3J of heat to melt it at 842°C. what would the heat of fusion for calcium?

Answer 1

To solve this problem, you'll need the formula that relates heat energy to mass and heat of fusion:

q = m·ΔHf

where

q = heat energy

m = mass

ΔHf = heat of fusion

Step-by-step explanation:

62.3J ÷ 7.3g = ΔHf

8.53 J/g = ΔHf

4.18 cal/g = ΔHf
