Question

0.10 moles of sodium sulfate is dissolved into 12 mL of solution. What is the molar concentration of the solution?
Your answer should have two significant figures (round your answer to one decimal place).

Answer 1

the molar concentration should be atleast 5mL off the solution since its disolved

Answer 2

Answer:

8.3

Explanation:

Convert mL to L.

12 mL×1 L1000 mL=0.012 L

Solve for molarity.

Molarity=moles of solute

liters of solution=0.10 mol0.012 L=8.3 M
