1. 1. Aqueous XO4 -3 ions form a precipitate with aqueous silver ions, Ag+. Write a balanced equation for the reaction, including state symbols.
2. When 4.18 mL of a solution of aqueous silver ions with a concentration of 0.2040 mol/L is added to a solution of XO4 -3 ions, 1.172g of the precipitate is formed.
a) calculate the amount in moles of Ag+ ions used in the reaction
b) calculate the amount in moles of the precipitate formed
c) calculate the molar mass of the precipitate
d) determine the relative atomic mass of X and identify the element
please help! my exam is on Monday, and this question will be on it!
thanks!
