1. The problem statement, all variables and given/known data "If a soft-drink bottle whose volume is 1.50 L is completely filled with water and then frozen to -10 degrees Celsius, what volume does the ice occupy? Water has a density of 0.997 g/cm^3 at 25 degrees Celsius; ice has a density of 0.917 g/cm^3 at -10 degrees Celsius." 2. Relevant equations D = m/V D = m/1500 mL m = x(0.997) + y(0.917) x + y = 1500 mL x = 1500 - y 3. The attempt at a solution m = (1500 - y)(0.997) + y(0.917) m = 1495.5 - y0.997 + y0.917 m = 1495.5 - y0.08 I feel like I would need the mass of the bottle's contents or its density in order to proceed. Am I plugging in my numbers wrong?
