Question

6 grams of sodium chloride (NaCl) is dissolved to create 0.5 L of solution. What is the

molarity of this solution?

Answer 1

0.206M

Step-by-step explanation:

Molarity, which refers to the molar concentration of a substance can be calculated using the formula as follows:

Molarity (M) = number of moles (n) ÷ volume (V)

According to the provided information, mass = 6grams, volume = 0.5L

Since molar mass of NaCl = 23 + 35.5

= 58.5g/lol

Mole = mass/molar mass

Mole = 6/58.5

Mole = 0.103mol

Hence;

Molarity = 0.103/0.5

Molarity = 0.206M
