55.

Calculate the molarity of each of the following solutions:

(a) 0.195 g of cholesterol, C27H46O, in 0.100 L of serum, the average concentration of cholesterol in human serum

(b) 4.25 g of NH3 in 0.500 L of solution, the concentration of NH3 in household ammonia

(c) 1.49 kg of isopropyl alcohol, C3H7OH, in 2.50 L of solution, the concentration of isopropyl alcohol in rubbing alcohol

(d) 0.029 g of I2 in 0.100 L of solution, the solubility of I2 in water at 20 °C

Step 1

(a)

Given data: 0.195 g of C27H46O in 0.100 L

Molecular weight of C27H46O =386.65 g/mol

Step 2

Hence, the molarity of the solution can be calculated as follows:

Step 3

(b)

Given data: 4.25 g of NH3 in 0.500 L

Molecular weig...
