Answer to Question #253120 in Inorganic Chemistry for chin

Question

Throat spray is used in relieving pain and irritation caused by sore throat, sore

mouth, or canker sores. It is composed of a diluted solution of Phenol in water.

The mass percent of the usual throat spray is 1.40% C6H5OH in water. The density

of the Phenol solution and Water are known to be 0.9956 g/ml and 1.00 g/ml

respectively. Calculate the Molarity of the solution. (10 pts)

Answer 1

Molar mass of C6H5OH= 94.11g/mol

1.4/100× 94.11= 1.32g

0.014/0.0019956

= 7.0154mol/L
