2. you need to prepare 150 ml of 150 mm aqueous solution of magnesium chloride hexahydrate. how much of the compound should you weigh? (mgcl2-4h20) i micromolar: 10-m 50, 150mm=16*10-4 m-molesse -.6x10-4. thules/.150l - 0.225x10-4 so, you should weigh (4.574 mg imol of magnesium chloride hexahydrate - 203.30279 1950, 0.228 x 10-4 moles of macl, 68,0 = 203.3027 x 0.225 x 10-4 = 0.004574310159: 4.574 mg
