## Homework Statement

"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."

## Homework Equations

D = m/V

D = m/1500 mL

m = x(0.997) + y(0.917)

x + y = 1500 mL

x = 1500 - y

## 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?
