Calculate the molarity of a solution containing 0.2 mol nh4br in exactly 200 ml solution

Molarity is calculated using the following equation:

number of moles solute / number of litres of solvent.

Number of moles = 0.2 moles (given)

1 litre = 1000 ml

Therefore, 200 ml = 0.2 litres

Using the previously mentioned equation, we can calculate molarity as follows:

Molarity = 0.2/0.2 = 1
