Answer 1

Answer #1

Mass of the sample = 460 mg

Molecular formula of the sample = C₂H₂Cl₂

Molar mass of the sample = 96.95 g/mol

Moles of the sample = 460 mg / 1000 x 96.95 g/mol = 0.004744713 Moles

Molar heat of the capacity = 7.19 Joules / 0.004744713 Moles = 1515.37 J / Mole K

Hence molar heat of the capacity of sample is 1515.37 J / Mole K
