Assuming no heat loss by the system, what will be the final temperature when 84.0 g of water at 10.0 oC are mixed with 46.0 g of water at 50.0 oC?

Calculate the amount of heat required to raise the temperature of an 91g sample of water from 39 ∘C to 65 ∘C.

The specific heat of toluene (C7H8), is 1.13 J/g•K. How many kJ of heat are necessary to raise the temperature of 65.3 g of toluene from 19.3 °C to 30.4 °C?

When 6.54 grams of Zn is placed in 500.0 mL of 1.00 M CuSO4(aq) in a coffee cup calorimeter, it reacts completely to displace copper. The temperature of the solution rises from 20.0˚C to 30.4˚C. Assume the coffee cup itself gains no heat and that the solution has the same density (1.00 g/mL) and specific heat (4.184 J/g˚C) as pure water. (a) How much heat does the solution gain during this reaction? (in J)

What is the heat capacity of 2.63 mol of liquid water?   How many kJ of heat are needed to raise the temperature of 2.60 kg of water from 41.1 oC to 70.9 oC?

If you combine 240.0 mL240.0 mL of water at 25.00 ∘C and 110.0 mL of water at 95.00 ∘C, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.

How much heat is required to raise the temperature of 3.90 g of water by 45°C?

If you combine 270.0 mL of water at 25.00 ∘C and 110.0 mL of water at 95.00 ∘C, what is the final temperature of the mixture? Use 1.00 g/mL as the density of water.

Assuming no heat loss by the system, what will be the final temperature when 65.0 g of water at 10.0 oC are mixed with 73.0 g of water at 50.0 oC?

A group of students place 15.41g of a metal into a test tube. They place the test tube into a beaker of boiling water until the temperature of the metal was 89.8°C. Then they quickly place the heated metal into a beaker of 10.47g of water with an initial temperature of 16.4°C. The temperature of the mixturecame to rest at 26.1°C. What is the specific heat of the metal used? (CH2O = 4.18 J/g°C)
