A sample of silver at 20.0 °C is heated to 100 °C when 1000 cal is added. What is the mass of the silver? (csilver = 0.056 cal/deg-gm)

  • physical science -

    The temperature change is 80 C.
    That is called "delta T"

    Use this formula:

    Q = M*C*(delta T)
    Q is the added heat energy.

    M = Q/[C*(delta T)]
    = 1000 Cal/[0.056 Cal/g C*80 C]
    = ___ gm
