Calculate the amount of heat required for the evaporation of 105.0 g of water at 100.0 c

To determine the amount of heat needed to evaporate a certain amount of water at its boiling point, we use the equation,

                  H = m(Hv)

where H is the heat, m is the mass (in grams), and Hv is the latent heat of vaporization. Substituting the known values,

                 H = (105 g)(540 cal/g)

                  H = 56700 cal

                H = 56.7 kcal

56.7 kcal

2.00 is the !
