Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Since natural gas (CHe 16.05 g/mol) and propane (CyHg, 44.11 g/mol) are colorless and odorless, a small amount of methanethiol is added to make it easy to detect a gas leak since humans can detect methanethiol in concentrations as low as only a few parts per billion. A sample of propane is analyzed and found to contain 2.50 mg of methanthiol in 1000.0 g of the mixture of the two gases. Which of the following statement is true? O methanethiol is the solute, propane is the solvent the vapor pressure of methanethiol is 2.5 mg/g propane is the solute, methanthiol is the solvent O The methanethiol must become a solid to dissolve in propane
