Question

Calculate the mass of water formed when 0.706 g of aluminum hydroxide reacts with excess hydrochloric acid according to the following reaction. Al(OH)3(s) + 3HCl(aq) - AlCl3(aq) + 3H2O(1) Your Answer: Answer Hinits

Answer 1

PAGE NO. DATE We know given for Calculate that any its if mass is compount we can No. of moles Given murs [Al (onz} = 0.70bg. Molecular whit Allon = 78 g/mol n (noot males) > Given wt. Molecular wb = 01706 2 78 know from recution We can I mol of nelong produce 3 mole of No Alloz. +3H Ucas) → All Uz cag) + 34,00) I We Say I mole of Allow - produce 3 moles of 4₂0 mole of Allons, a produce 3 0.706 708 0-706 mole 708 of the Mole of 10 = 3x0.706

n Given wt. Molecular wt Moleculas t (120) = 1891 mol 30.706 aut. of mo et of 40 = 3X18X0.706 78 wt of 50 = 0.4888 g -
