Question

if 3.38 mol magnesium and 3.38 mol.of hydrochloric acid react how many grams of magnesium chloride are produced

Answer 1

4.18 MgCl2

Step-by-step explanation:

Answer 2

Mg+2HCl------- MgCl2 +H2

2 moles ofHCl use 1 mole of Mg

3.91 mol of HCl=1/2 *3.91

Moles of Mg used = 1.955 moles

Moles of HCl used=3.91 mol

1 mole of Mg make 1 mole of MgCl2

So moles of MgCl2=1.955 moles

Molar mass=24+ (35.5*2)

Molar mass= 95 g/ mol
Mass of MgCl2 produced=moles *molar
