It is known that 10 grams of the substance and 90 milliliters of water are required to obtain a 10% solution. or in the case of 1 liter 100 grams of substance and 900 ml. water.
But the problem is that BaCl2 contains 2 molecules of water. they can not calculate and get the desired concentration.
I recently work in a chemical lab and I need a BaCl2 solution to determine the concentration of Na2CO3 in the samples.
Tank you!

If it is to precipitate the carbonate you don't need a really high accuracy, ignore water of crystallization and just calculate how much dihydrate contains enough of just BaCl
