if 500 ml of HCl solution is needed to react with 2.43 g of Mg, what is the molarity of the HCl solution?
Mg + 2HCl ==> NgCl2 + H2
mols Mg = grams/molar mass
Convert moles Mg to moles HCl using the coefficients in the balanced equation.
Convert moles HCl to volume using M = moles/L.
The hydrogen generated in lab is a product of reaction between magnesium and hydrochloric acid. Which of these reacts was the limiting reactant?
