Self Test 8.1

Self-Test 8.1 Water expands when it freezes. How much work does 100g of water do when it freezes at 0.0 C and pushes back the metal wwall of a pipe that exerts an opposing pressure of 1070 atm? The densities of water and ice at 0.0 C are 1.00gcm3 and .92 gcm3, respectively. [Answer: w=.86kJ]

How would you go about solving this? I understand the equation is w=-PdeltaV, but I haven't been getting the right answer.
