Calculating Mass of Solution for Temperature Change in HCl-Water Mixture

[Meddie]

Hello, I am trying to do a lab for Ap chemistry, but I am a bit confused on how to do the following:

Calculate the mass of solution that underwent the temperature change, assuming the density of HCl is the same as water

 

[Borek]

What is given to you?

 

[Meddie]

Mass of solution: 60.0 g
Initial Temperature: 22.7 degrees celsius
Final temperature: 37.9 degrees celsius

thats pretty much it.

 

[Borek]

So mass of the solution is 60.0g, period. Nothing to calculate.

Unless you have not told everything.
