Question

Quizplus · Accepted Answer

First, we need to find the molar mass of tetraphenylarsonium chloride dihydrate, which is: 1 mol tetraphenylarsonium chloride dihydrate = 697.55 g/mol Next, we need to find the molar ratio between tetraphenylarsonium chloride dihydrate and H₂O. According to the balanced equation: 1 mol tetraphenylarsonium chloride dihydrate = 1 mol H₂O Now we can use dimensional analysis to find the amount of H₂O in 10.0 g of tetraphenylarsonium chloride dihydrate: 10.0 g tetraphenylarsonium chloride dihydrate x (1 mol/697.55 g) x (1 mol H₂O/1 mol) x (106.16 g/1 mol) = 0.792 g H₂O Therefore, the answer is B) 0.792 g.
