Answer to Question #235128 in General Chemistry for cat

Question

Calculate the heat change in kilocalories for condensation of 6.5 kg of steam at 100 ∘C.

Answer 1

Every 1 gram of water at 100° C absorb 540 calories

So,

Total water = 6.5 kg = 6,500 gram

So,

6,500 gm of steam require = 6,500 x 540

6,500 gm of steam require= 3,510 kilo calories (approx)
