Chemistry

Magnesium sulfate has a number of uses, some of which arerelated to the ability of the anhydrate form to remove water fromair and others based on the high solubility of the heptahydratc(MgSO.4 . 7H2,O)form, also known as Epsom salt. The densities ofthe anhydrate and heptahydratc crystalline forms are 2.66 and 1.68g/mL, respectively. Suppose you wish to form a 20.0 wt% MgS()4aqueous solution by simply pouring crystals of one of the formsinto a tank of water while the temperature is held constant at30degree C. The specific gravity of the 20.0 wt% solution at30degree C is 1.22. Answer the following questions for both formsof the MgS04 crystals: What volume of water should be in the tankbefore crystals arc added if the final product is to be 1000 kg ofthe 20wt% solution? Suppose the tank diameter is 0.30 m. What isthe height of liquid in the tank before the crystals are added?What is the height of the water in the tank after addition of thecrystals but before they begin to dissolve? What is the height ofliquid in the tank after all the MgSO4 has dissolved?5.8. Use theidcal-gas equation of state to kg/m3 at 40degree C

a the final product is to be 1000Kg of the 20wt solution 20wt solutio means 20grams of Magnesium in 100g of solution so in 1000Kg of solution the amount of salt needed 200Kg so for each salt we will add 200Kg of salt in See Answer
