As we learnt

 

Molarity -

 Molarity (M) = (Number of moles of solute)/(volume of solution in litres)

 

- wherein

It is defined as the number of moles of the solute in 1 litre of the solution.

 

 192 g of SO42- = 2 moles of SO42-

2 moles of SO42- \rightarrow 2 moles of BaSO4 

Volume = \frac{no. of moles}{molarity} =\frac{2}{2} = 1L

 

 

 


Option 1)

0.5 L

Option 2)

1 L

Option 3)

2 L

Option 4)

1.5 L
