Question

How many moles of H are there in 1 dm3 of 0.5M solution​

Answer 1

Moles of H = 0.5 moles

Step-by-step explanation:

Molarity = It is defined as the moles of the solute present in one litre of the solution. It is used to measure the concentration of the solution. Molarity is represented by "M".

`Molarity =(moles)/(volume(L))`

0.5 M means = 0.5 moles are present in one litre of the solution

Volume = 1 dm3 =1 litre

1 litre = 1 dm 3 ( both are equal )

Calculation:

`Molarity =(moles)/(volume(L))`

`moles = Molarity* volume(L)`

`moles = 0.5* 1`

Moles = 0.5 mole

Hence ,

0.5 ,moles of H are present in 0.5M of the solution.
