Physics question on Energy

  1. May 1, 2009 #1
    1. The problem statement, all variables and given/known data

    Glycerin, a major component of soap, is heated before being poured into moulds. Calculate the mass of glycerin if 5.50 x 10^3 J of energy causes a 4.20°C temperature rise.


    2. Relevant equations
    Q = C*M*(T2-T1)

    I need to look up C which is specific heat for glycerin. I think its 2400 Jkg-1K-1. Or 2.4. I'm not sure

    Q = 5.5x10^3 J
    T2-T1 = 4.2
    C=?



    3. The attempt at a solution

    I got m= 545.634921 g when I plugged in 2.4 as c.
    and m= 0.545634921 g when I plugged in 2400 as c.
