If you weigh out a piece of mg to a mass of 0.0240 g what is the minimum volume of 1.00 m hcl needed to ensure that the mg is the limiting reactant?

1.97 ml.

Mg reacts with HCl at a 1:2 ratio.

Mg + 2 HCl → MgCl₂ + H₂.

How many moles of atoms in 0.0240 g of Mg?

The molar mass of Mg is 24.305 g/mol. In other words, the mass of one mole of Mg atoms is 24.305 gram.

.

How many moles of HCl does it take to oxidize that of Mg?

It takes 2 moles of HCl to oxidize 1 mole of Mg. As a result, it takes to oxidize of Mg.

Mg is the limiting reactant, meaning that HCl is in excess. There needs to be more than HCl for Mg to be the limiting reactant.

How many liters of 1.00 M HCl?

1.00 M is the same as 1.00 moles per liter.
