Calculate the number of molecule in 5g of steam

1.	Calculate the number of molecule in 5g of steam
Answer» ergy required for5gm of water at 0 ∘ Cto get converted to water at 100 ∘ C is latent HEAT required + heat required to change its TEMPERATURE by 100 ∘ =(80⋅5)+(5⋅1⋅100)=900calories.Now,heat liberated by 5gm of steam at 100 ∘ C to get converted to water at 100 ∘ C is 5⋅537=2685 caloriesSo,heat energy is ENOUGH for 5gm of ice to get converted to 5gm of water at 100 ∘ CSO,only 900 calories of heat energy will be liberated by steam,so amount of steam that will be converted to water at the same temperature is 900537=1.66gSo,the final temperature of the mixture will be 100 ∘ C
