Establish the molality equation and determine the molality of a mixture of 9.52 g heptane (C7H16) and 87 g benzene (C6H6)
Recall that molality can be calculated as:
In this case, we need to convert the mass of heptane to moles and mass of benzene to kg
Determine the molality of a solution prepared by dissolving 9.52 g of heptane (C7H16) (100.2 g/mol) in 87 g of benzene (C6H6). Give your answer to 2 decimal places.
a. 1.09 m
b. 1.21 m
c. 1.56 m
d. 2.61 m
e. 1.28 m
