Calculate the number of moles in a liquid sample of a substance that has a molar heat of fusion of 3.811 kJ/mol, if the sample releases 90.6 kJ when it freezes. Answer in units of mol Calculate the molar mass of the substance if the mass of the sample is 2022 g. Answer in units of g/mol.

23.77mole,85.1g/mol

Explanation:

the moles of liquid is 23.77mole which is obtained by divide 90.6kj to 3.811kj/mol and molar mass is obtained from the formula of mole eg mole=mass/molar mass but mass is given and moles is obtained above.
