What volume of water would be required to dissolve 1 g of BaF2?
mass of BaF2 is 1.31 g and it dissolves in 1 L of water. The answer is 0.763. Can someone please explain how they got this?
One gallon of water dissolves 1.31 g. If you put in more BaF2 than that, the solution is saturated and the remainder will not dissolve.
1 g of BaF2 is 1/1.31 or 76.3% of the amount that will saturate one gallon of water.
If you use 76.3% of 1 gallon of water, you will have a saturated solution.
