How many grams of sodium chloride are there in 550 ml of a 1. 90 m aqueous solution of sodium chloride?

Sagot :

There are 61.06 grams of of sodium chloride in its aqueous solution.

An aqueous solution is the one in which solvent is always water. Water is the most used universal solvent.

According to the question,

Volume of water = 550 ml = 0.55 L

Molarity of solution = 1.90 M

Formula for molarity = moles of solute / volume of solvent

1.90 =  moles of solute / 0.55 L

Moles of solute = 1.90 × 0.55 L = 1.045 moles

Now, moles = mass / molar mass

molar mass of NaCl = 58.44 g/mol

Therefore, 1.045 = mass / 58.55 g/mol

Hence, mass in grams = 1.045 × 58.44 g/mol

Mass = 61.07 grams
