How much heat (in cal) is necessary to heat 27.0 mL of octane (s= 0.526 cal/g ®C ; d = o.703 g/mL ) from 50.6 ®C to 67.2 ®C?
I understand the Delta T is = 16.6®C
But I don’t know what d stands for (density) or how to apply to the formula.

  • chemistry - ,

    Use density to convert mL octane to grams octane. mass = volume x density.

    Then q = heat needed = mass octane x specific heat octane x delta T.
