The specific heat capacity of a metal is given as 0.745 J/ degree Celcius.What mass of the metal must be heated to 95 degree Celcius in order to be used to warm 2.548 L of water from 18.1 degree Celcius to 22.5 degree Celcius ?

I'm so confused I don't even know where to start
I know that Q= m•s•delta T
I'm thinking to rearrange the equation to
m=q/s•Delta T

I don't know I think what's really throwing me off is the 95degree Celcius

  1. Note the correct spelling of celsius.
    You have half of it but not the other half. The metal is heated to 95 C then placed in the water. Then heat lost by the metal + heat gained by the water = 0
    heat lost by metal is
    q = mass metal x specific heat metal x (Tfinal-Tinitial)

    heat gained by the water is
    q = mass H2O x specific heat H2O x (Tfinal-Tinitial)

    Set the sum of these to zero and you have it.
    [mass metal x specific heat metal x Tfinal-Tinitial)] + [mass H2O x specific heat H2O x (Tfinal-Tinitial)] = 0
    [mass metal x 0.745 x (22.5-95)] + [2548 x 4.184 x (22.5-18.1)] = 0
    Only one unknown.
