a student adds 0.5 moles of solute to enough water to form 500 ml of solution what is the concentration of the solution he made

Sagot :

Answer: The concentration of solution made by the student is 1 M.

Explanation:

Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.

The formula used to calculate molarity:

[tex]\text{Molarity of solution}=\frac{\text{Number of moles of solute}\times 1000}{\text{Volume of solution (mL)}}[/tex]       .....(1)

Given values:

Moles of solute = 0.5 moles

Volume of solution = 500 mL

Plugging values in equation 1:

[tex]\text{Molarity of solution}=\frac{0.5\times 1000}{500}\\\\\text{Molarity of solution}=1M[/tex]

Hence, the concentration of solution made by the student is 1 M.
