Answer 2

Correct question:-

Find the number of moles of solute present in 0.5dm³ of 0.5 M solution.

Given:-

→ Volume of solution = 0.5 dm³

→ Molarity of the solution = 0.5 M

To find:-

→Number of moles of solute

Solution:-

Firstly, let's convert the volume of the solution from dm³ into L.

=> 1 dm³ = 1L

=> 0.5dm³ = 0.5(1)

=> 0.5 L

Let the required number of moles of solute be x.

Molarity of a solution:-

= Moles of soute/Liters of solution

=> x/0.5 = 0.5

=> x = 0.5(0.5)

=> x = 0.25 mole

Thus, the number of moles of solute

is 0.25.
