Question

What is the molar concentration of a solution of 9.88 g MgSO, dissolved in 75 mL water ?​

Answer 1

Answer: The molar concentration of solution is 1.10

Step-by-step explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

`Molarity=(n* 1000)/(V_s)`

where,

n = moles of solute

`V_s` = volume of solution in ml

moles of
`MgSO_4` =
`\frac{\text {given mass}}{\text {Molar mass}}=(9.88g)/(120g/mol)=0.0823mol`

Now put all the given values in the formula of molality, we get

`Molarity=(0.0823* 1000)/(75)=1.10`

Therefore, the molar concentration of solution is 1.10
