Questions & Step-by-Step Solutions

If the latent heat of fusion of ice is 334 J/g, how much heat is required to melt 50 g of ice? (2019)
  • Step 1: Identify the mass of ice you want to melt. In this case, it is 50 grams.
  • Step 2: Identify the latent heat of fusion of ice, which is given as 334 Joules per gram (J/g).
  • Step 3: Use the formula to calculate the heat required: Heat required = mass × latent heat.
  • Step 4: Substitute the values into the formula: Heat required = 50 g × 334 J/g.
  • Step 5: Perform the multiplication: 50 × 334 = 16700 J.
  • Step 6: Conclude that the heat required to melt 50 g of ice is 16700 Joules.
