136 grams of barium sulfate are used to make a 2.5 m solution. how many liters of water are needed?

0.23 L

Explanation: Molarity of solution is defined as the number of moles of solute dissolved per liter of the solution.

Formula used :

where,

n= moles of solute

= volume of solution in L

Now put all the given values in the formula of molarity, we get

Therefore, the volume of solution in Liters is 0.23.
