In an experiment, 10.0 g of magnesium reacted with excess hydrochloric acid forming magnesium chloride. Mg(s) +2HCl(aq) → MgCl2(aq) +H2(g)
At the completion of the reaction, 29.5 g of magnesium chloride was produced. Calculate the percent yield. (Pls help)

Respuesta :

Answer: 75.3%

Explanation:


Mg molar mass = 24

MgCl2 molar mass = 94

—> 94 x 10 / 24

29.5/1 x 24/94 x 10


= 29.5 x 24 / 94 x 10


since we are looking for percentage yield we multiply by 100


= 29.5 x 24 x 100 / 94 x 10 = 75.3%
