What is the concentration of a solution that has 15.0 g NaCl dissolved to a total of 750 ml?

Oksana_A [137]

<u>Answer:</u> The concentration of solution is 0.342 M

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (Sodium chloride) = 15 g

Molar mass of sodium chloride = 58.5 g/mol

Volume of solution = 750 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{15g\times 1000}{58.5g/mol\times 750mL}\\\\\text{Molarity of solution}=0.342M$

Hence, the concentration of solution is 0.342 M

I got this stupid question wrong so that you people don't have to. I simply hate chemistry and I wish it didn't exist. Kind of like this website that makes me explain the answer.

Trust me, the answer is correct

Calculate the molarity of the solution.

IRISSAK [1]

<span>The formula given for it is
moles = given wt/mol.Wt

Mol.wt of nacl
nacl=23+35.5
=58.5 gm
Moles = 29/58.5
= 0.495
~ 0.15 moles </span>
