How much energy, in calories, will be required to evaporate 125.0 mL of ethanol at its boiling point?

Given:
Density 0.818 g/mL
Boiling Point 78.5 C
Heat of Vaporization 210 cal/g

Any help is appreciated!

• Chemistry -

Use density to convert 125.0 mL ethanol to grams. mass = volume x density
q = mass ethanol x deltaHvap = ??
