A 350g glass beaker contains 500g of water at a temperature of 10.0°C. If 400g of ethyl alcohol at 35°C is subsequently poured into
the beaker and the water and alcohol mixture is thoroughly stirred, what is its equilibrium temperature?

The glass and the water start out at 10 C and get warmer as they gain heat from the ethyl alcohol, initially at 35 C. Look up the specific heats of alcohol, glass and water.
Write an equation that says the heat gained by the water and glass equals the heat lost by the alcohol. The only unknown should be the final temperature, which you can then solve for.
