1.	If 900 joule per gram of heat is exchanged at boiling point of water then what is increase in entropy. Please give answer in joule per mole
Answer» If 900 joule PER gram of HEAT is exchanged at boiling point of water then what is increase in entropy. Please give answer in joule per MOLE... solution : given, 900J/g of heat is exchanged at boiling point lf water. we know, molecular mass of water = 18g/mol so, heat required per mole , H = 900 × 18 J/mol boiling point of water in Kelvin = 373K now, entropy = heat/boiling point of water in Kelvin. = 900 × 18/373 = 43.4 J/mol/K

If 900 joule PER gram of HEAT is exchanged at boiling point of water then what is increase in entropy. Please give answer in joule per MOLE...

solution : given, 900J/g of heat is exchanged at boiling point lf water.

we know, molecular mass of water = 18g/mol

so, heat required per mole , H = 900 × 18 J/mol

boiling point of water in Kelvin = 373K

now, entropy = heat/boiling point of water in Kelvin.

= 900 × 18/373

= 43.4 J/mol/K
