In the laboratory you are asked to make a 0.175 m barium sulfide solution using 15.4 grams of barium sulfide. How much water should you add

0.5195 liters of water

Explanation:

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

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

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.

b.false that your answer
