mass = 140 g of NaBr
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
mol of NaBr :
= mass : MW
= 140 g : 102,894 g/mol
= 1.361
Molarity :
= 1.361 mol : 3 L
= 0.454 M
