Answer:

0.5195 liters of water

Explanation:

First we convert 15.4 grams of barium sulfide (BaS) into moles, using its molar mass:

  • 15.4 g ÷ 169.39 g/mol = 0.0909 mol

Then we calculate the required volume of water, using the definition of molarity:

  • molarity = moles / volume
  • 0.175 M = 0.0909 mol / Volume
  • Volume = 0.5195 L
