Answer to Question #158682 in General Chemistry for Maryam

Question

How many grams of HCL are consumed by the reaction of 2.50 moles of magnesium?

Answer 1

Reaction between Mg and HCl

Mg + 2HCl = MgCl₂ + H₂

Molar mass of HCl = (35.5 +1) = 36.5 gmol^-1

So 1 mol Mg consume 2 mol HCl =( 2×36.5) g HCl

So 2.5 mol Mg consume = (2×36.5×2.5)

= 182.5 g HCl
