Calculate the enthalpy change when 245 g of ice melts. Strategy The H fus value in Table

Question:

Calculate the enthalpy change when 245 g of ice melts.

Strategy The ΔH_fus value in Table 9.3 is in J/mol, so the amount of ice must be converted into moles. Multiplying the number of moles by ΔH_fus will provide the desired quantity.

Table 9.3
