Molarity to Grams Formula
The formula to convert molarity to grams is:
G = M * V * M.wt
- G = Grams
- M = Molarity (mol/L)
- V = Volume of the solution
- M.wt = Molecular Weight (molar mass) of the substance
How to Convert Molarity to Grams?
To convert from molarity (moles per liter) to grams, you need to know the molar mass of the substance and the volume of the solution.
Here’s a step-by-step process of M to grams:
- Determine the molarity (M)
- Determine the volume of solution
- Determine the molecular mass with the help of the periodic table
- Put all values into the above formula
Solved Example
Example – A 1 M (molar) solution of sodium chloride (NaCl) and you have 0.5 liters of the solution then calculate the mass in grams of NaCl solution.
Solved –
Given, Molarity = 1 M, Volume of solution = 0.5 liter
The molar mass of NaCl = 58.44 g/mol
Grams = 1 * 0.5 * 58.44 = 29.22 g
29.22 grams of sodium chloride
