Answer #1

Solute is the component which is present in less amount in a solution and the solvent is the component present in higher amount in a solution.

In the given solution, CsSO4 is solute and water is solvent.

No.of moles of solute = mass / molar mass = 5.4893 / 228.96 = 0.02397 mol

Volume of the solution = 100 mL = 0.1 L

Molarity = no.of moles of solute / volume of the solution (L)

Molarity = 0.02397 / 0.1 = 0.2397 M    <<<<<<--------(ANSWER)

When chemists work with solid materials, we simply weigh out amounts of solid reagents and calculate mole amounts when thinking about stoichiometry. However, when we dissolve a solid (also known as a solute) in a solvent to form a solution, the solute becomes evenly distributed throughout the solution and we need to know how many moles of solute are present in a particular volume of solution. A solution is created by dissolving 10.0 grams of ammonium chloride in enough water...
