How much energy does it take to melt 2 kg of ice? (Refer to table of
constants for water.)
1 mol
O A. 2 kg > 1000 g/kg *
18.02 g
X
x 40.65 kJ/mol = 4512 kJ
1 mol
B. 2 kg x 1000 g/kg *
*(-285.83 kJ)/mol = -31,724 kJ
18.02 g
O C. 2 kg > 1000 g/kg x
1 mol
18.02 g
x 6.03 kJ/mol = 669 kJ
O D. 2 kg > 1000 g/kg *
1 mol
18.02 g
x 4.186 kJ/mol = 465 kJ
