Question

What is the molarity of 2.00 L of a solution that contains 14.6 g NaCl?

Thank you so much I am having a tough time with this one.

Answer 1

Answer: The molarity of the solution is 0.125 M

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)/(V_s)`

where,

n = moles of solute

`V_s` = volume of solution in L

moles of
`NaCl` =
`\frac{\text {given mass}}{\text {Molar mass}}=(14.6g)/(58.5g/mol)=0.250mol`

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

`Molarity=(0.250mol)/(2.00L)=0.125M`

Therefore, the molarity of the solution is 0.125 M
