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

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

False because saturated fatty acids contain only single bond
