Calculate the Heat Required to Transform 18 G of Ice \rightarrow

Question 48

Multiple Choice

Calculate the heat required to transform 18 g of ice at 0°C to water vapor at 100°C using some or all of the data given below.
H2O(s) \rightarrow H2O(l)   Δ\Delta Hrxn° = 6.03 kJ/molrxn
H2O(l) \rightarrow H2O(g)   Δ\Delta Hrxn° = 40.67 kJ/molrxn
2 H2(g) + O2(g) \rightarrow 2 H2O(g)   Δ\Delta Hrxn° = -484 kJ/molrxn
H2O(liquid, 0°C) \rightarrow H2O(liquid, 100°C)   Δ\Delta Hrxn° = 7.53 kJ/molrxn


A) 40.67 kJ
B) 46.70 kJ
C) 54.23 kJ
D) 296 kJ
E) none of these
