Given that the molar mass of nacl is 58.44 g/mol, what is the molarity of a solution that contains 87.75 g of nacl in 500. ml of
solution?
moles of solute
use molarity - liters of solution

Molarity = 3 M

Explanation:

Given data:

Molarity of solution = ?

Mass of sodium chloride = 87.75 g

Volume of solution = 500 mL (0.5 L)

Solution:

Number of moles = mass/ molar mass

Number of moles = 87.75 g/ 58.44 g/mol

Number of moles = 1.5 mol

Molarity:

Molarity = number of moles / volume in litter

Molarity = 1.5 mol / 0.5 L

Molarity = 3 M

so what is the problem with your lab report and whats the subject of the lab report? i will you
