Question

find molarity if o.580 moles of a compound dissolve in 200ml of its solution​

Answer 1

use molarity formula that is

= moles of solute/litres of solution

according to your question

Molarity = 0.580/0.2

=2.9

Answer 2

The molarity of given solution is 2.9 M.

Explanation:

As we know that molarity is the number of moles present in liter of solution.

Mathematically,    Molarity = $\frac{\text{no. of moles}}{\text{volume in liter}}$

It is given that moles of given compound is 0.580 mol and its volume is 200 ml. As there are 0.001 liter present in 1 ml so, 200 ml will be equal to 0.2 liter.

Therefore, calculate the molarity of given solution as follows.

        Molarity = $\frac{\text{no. of moles}}{\text{volume in liter}}$

                     = $\frac{0.580 mol}{0.2 liter}$

                     = 2.9 M

Therefore, we can conclude that the molarity of given solution is 2.9 M.
