How long would it take (in seconds) to heat 215.2ml of water from 20∘C to 78.0∘C using a heater with a power rating of 50 W (i.e., it puts out 50 Joules of energy every second)?

For water: use 334 kJ/kg for the latent heat of fusion, 2.26×103 kJ/kg for the latent heat of vaporization, and 4.19 kJ/kg∘C for the specific heat. Also for water: remember that 1ml has a mass of approximately 1 g.
