How do you convert molarity to moles?
To calculate the number of moles in a solution given the molarity, we multiply the molarity by total volume of the solution in liters.
How do you calculate moles from molarity and volume?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
