Question

How much heat does your body lose when 2.65 g of sweat evaporates from your skin at 25 ∘C? (Assume that the sweat is only water.) The heat of vaporization of water at 25 ∘C is 44.0 kJ/mol.

Answer 1

q = mass H2O x 44.0 kJ/mol = ?
Remember to convert the H2O to mols. mols = grams/molar mass = ?
