Achemist wants to produce 12.00 grams of barium sulfate by reacting a .6000 m bacl2 solution with excess h2so as show in the reaction below. what volume of the barium chloride should be used?
bacl2 + h2so4 --> baso4 +2hcl

0.0857 L

Explanation: It's a stoichiometry problem. Balanced equation is given from which there is 1:1 mol ratio between and .

Chemist wants to produce 12.00 grams of barium sulfate by reacting a 0.6000 M barium chloride solution with excess sulfuric acid.

We know that molarity is moles of solute per liter of solution. Molarity of barium chloride is given. If we know its moles then its volume could easily be calculated.

From given grams of barium sulfate, we calculate its moles and then using mol ratio we calculate the moles of barium chloride.

Molar mass of barium sulfate is 233.38 gram per mol.

The complete set up is shown below using dimensional analysis:

= 0.0857 L

So, 0.0857 L or 85.7 mL of should be used.

answer; ///(d) the correct answer is double or triple

the answers would be

the first one and the second one
