The term hydrate would mean that the compound contains water molecules. When this compound is heated, the water molecules are lost first which means that what remains would be the dried compound. Therefore, the H2O lost from the hydrate would be 6.00g - 3.27g = 2.73 g.
Disodium inosinate is the disodium salt of inosinic acid with the chemical formula C10H11N4Na2O8P. It is used as a food additive and often found in instant noodles, potato chips, and a variety of other snacks. Although it can be obtained from bacterial fermentation of sugars, it is often commercially prepared from animal sources.
You can use fractional distillation
Number of moles:
n = sample mass / molar mass
n = 15.00 / 74.6
n = 0.2010 moles of KCl
Therefore:
Molarity = moles / Volume
0.1107 = 0.2010 / V
V = 0.2010 / 0.1107
V = 1.815 L
