QUESTION:
A 122-mL sample of a 1.2 M sucrose solution is diluted to 500.0 mL. What is the molarity of the diluted solution?
ANSWER:Step 1 of 2
Volume of initial concentrated solution = 122-mL
Molarity of initial concentrated solution = 1.2 M
Volume of diluted solution = 500.0 mL
Molarity of diluted solution = ?
Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.
To calculate the molarity of the diluted solution, we use the formula :
Where, and
= Molarity and volume of initial concentrated solution.
and
= Molarity and volume of final diluted solution.
