What is the total amount of heat required to completely vaporize a 100.0 g of water at its normal boiling point?

Work too pls !!

The total amount of heat : 225.704 kJ

Heat of vaporization(ΔH vap) : heat needed to vaporize 1 mole of water , units : kJ/mol

For water at boiling point (100 °C) : ΔH vap = 40.66 kj/mol

mole of 100 g water :

so total Heat :

o conteúdo de calor de um sistema é igual à entalpia apenas para um sistema que é constante
