You take a jug of water from the refrigerator, and pour 240mL of it into a glass. The temperature of the beverage is 10.5ºC. You then add one 45g ice cube at 0ºC.(adsbygoogle = window.adsbygoogle || []).push({});

Determine the final temperature and the amount of ice remaining if any.

I've tried to work it out below, but my I must've made an error because the temperature has to be between 0 and 10.5. Where have I gone wrong?

4.184*240(x-10.5) = -[45*333+4.184*45(x-0)]

1004.16x - 10543.68 = -[29970+376.56x]

1004.16x - 10543.68 = -29970-376.56x

1,380.72x - 10543.68 = -29970

1,380.72x = -19,426.32

x = -19,426.32/1,380.72

x = -14.06970276

thanks
