solution:-



Given

Temperature = 0oC




Heat = 2.25k j




Mass= ?




So


By using


"\\Delta Q = mL_{fusion \\space of \\space ice}"


"\\Delta Q" = heat = 2.25 kilo joule = 537.7629 gram calorie


m = mass


"L_{fusion \\space of \\space ice}" = latent heat of fusion of ice = 80 cal/gm



By putting values in formula


m = "\\Delta Q \\over L_{fusion \\space of \\space ice}"


m = "537.7629 \\over 80"


Answer

"\\boxed{m = 6.72203625 gram}"
