Step 1
Solution stoichiometry involves the calculation of concentration of solutions in the given conditions of volumes, moles etc.
Solution stoichiometry is mainly based on the calculation of moles and volumes. These two values are used to calculate the molarity of solution. The relation between moles, volume and molarity is as given below;
Molarity=Moles of solutevolume of solution in L
Moles=Mass of solute in gMolar mass of solute (g/mol)
Step 2
The balance reaction of Mg with Cl2 is:
Mg(s)+Cl2(g)MgCl2(s)
Step 3
Calculate the moles of Mg from the given moles of Cl2
Moles of Cl2=2 moles
1 mole of Cl2 reacts with=1 mole of Mg
Hence moles of Mg=2 moles
Step 4
Calculate the mass of Mg:
Molar mass of Mg=24 gmol
Moles=Moles of solute in gMolar mass of solute (g/mol)
2 moles=mass24 gmol
Mass of Mg=2×24=48g
Step 5
Answer:
Mass of Mg =48g
