Verona dissolves 20. grams of nacl with water to make a 100 ml solution. what is the molarity of the solution? there are 1,000 ml in 1 l o a. 3.4 m o b.0.34 m o g.58 m o d. 20. m

b.0.34 M

Explanation:

Given that:

Mass of NaCl = 20 grams

Molar mass of NaCl = 58.44 g/mol

The formula for the calculation of moles is shown below:

Thus,

Given that volume = 100 mL

Also,

So, Volume = 100 / 1000 L = 0.1 L

Considering:

Molarity = 0.34 M

the answer is true.
