Answer:
Molarity of a 5.0 L solution that contains 0.5 moles of KNO3 is 0.1 M
Explanation:
Molarity : It is used to express the concentration of the solution and defined as total moles of solute present in one liter of solution .

Moles of KNO3 = 0.5 (given)
Volume of solution = 5.0 L
Substitute the value in given formula ,
 
 
on calculation,
Molarity = 0.1 mol/L
Molarity = 0.1 M
(M = mol/L)

Answer:
10 Litre
Explanation:
Given that ::
v1 = 25L ; n1 = 1.5 mole ; v2 =? ; n2 = (1.5-0.9) = 0.6 mole
Using the relation :
(n2 * v1) / n1 = (n2 * v2) / n2
v2 = (n2 * v1) / n1
v2 = (0.6 mole * 25 Litre) / 1.5 mole
v2 = 15 / 1.5 litre
v2 = 10 Litre
