Respuesta :
Answer : The mass of a sample of water is, 888.89 grams
Explanation :
Latent heat of vaporization : It is defined as the amount of heat energy released or absorbed when the liquid converted to vapor at atmospheric pressure at its boiling point.
Formula used :
[tex]q=L\times m[/tex]
where,
q = heat = 2000 kJ = [tex]2\times 10^6J[/tex] (1 kJ = 1000 J)
L = latent heat of vaporization of water = [tex]2.25\times 10^6J/kg[/tex]
m = mass of sample of water = ?
Now put all the given values in the above formula, we get:
[tex]2\times 10^6J=(2.25\times 10^6J/kg)\times m[/tex]
[tex]m=0.88889kg=888.89g[/tex] (1 kg = 1000 g)
Therefore, the mass of a sample of water is, 888.89 grams
