What is the molarity of a sodium carbonate solution containing 32.52 g Na2CO3 dissolved in enough water to make 822 ml of solution? NEED ASAP PLEASE!!

The molarity of a Sodium carbonate solution : 0.373 M

Given

32.52 g Na₂CO₃

822 ml of solution = 0.822 L

Required

The molarity

Solution

Molarity shows the number of moles of solute in every 1 liter of solution.

mol of solute = mol of Na₂CO₃ :

= mass : MW Na₂CO₃

= 32.52 g : 106 g/mol

= 0.307

Molarity :

= n : V

= 0.307 mol : 0.822 L

= 0.373 M

the answer is d.) potassium
