Answer:

177.213 grams

Explanation:

Given:

Total amount of water = 364 grams

Latent heat of fusion = 333 kJ/kg

Heat transferred = 62.2 kJ

The amount of water frozen = 62.2/333 = 0.186786 kg = 186.786 grams

Hence, the amount of water remained unfrozen = Total water - Amount of water frozen

the amount of water remained unfrozen = 364 grams - 186.786 grams = 177.213 grams
