How many moles of sucrose are contained in each solution?
(a) 3.4 L of a 0.100 M sucrose solution
(b) 0.952 L of a 1.88 M sucrose solution
(c) 21.5 mL of a 0.528 M sucrose solution
Solution:
Step 1
(a) 3.4 L of a 0.100 M sucrose solution
Molarity of sucrose solution = 0.1 M
Volume of solution = 3.4 L
It is known that , Molarity(M) =
Moles of solute = (molarity) (volume of solution)
= 0.1m/L 3.4 L = 0.34 mol
