How much ice (in grams) would have to melt to lower the temperature of 53.4g of water from 65 C to 0C?

I know there are more than one step here, I would appreciate an answer that does not do the work for me, but show me how to lay out the problems and in which order... thank you!

  • Chemistry -

    the sum of heats gained is zero.

    Heatgainedicemelting+heatgainedwater=0
    massice*Hf+53.4grams*specificheatwater*(0-65)=0

    massice=53.4g*1cal/gramC *53.4C / 80cal/g

    = 53.4*65/80 grams

    Thank you Bob for your time! I believe there was a misunderstanding in the question,my mistake... C is equal to degree celcius.

  • Chemistry -

    Note the correct spelling of celsius.
    Celsius is all that is needed. It need not be converted to kelvin.

    Thank you again!
