Question

A sample of 76 g of NaCl is dissolved to make 1 L of solution. What is the molarity of the solution? Show your work.

Answer 1

Molarity = Moles/Liters

Convert the 76g of sodium chloride to moles using

Moles = Grams/Molecular Mass

You can find the molecular mass by referring to a periodic table and adding the molecular mass of sodium with that of chlorine, the units of molecular mass are g/mol

There are also a billion tutorials on how to convert the mass of a compound to moles so just google if you dont understand my explanation
