Question

Calculate the number of moles of magnesium, chlorine, and oxygen atoms in 7.40 moles of magnesium perchlorate, Mg(ClO4)2. Express the number of moles of Mg, Cl, and O atoms numerically, separated by commas.

Answer 1

Number of moles Magnesium (Mg) = 7.40 moles

Number of moles Chlorine (Cl) = 14.8 moles

Number of moles of oxygen atoms = 29.6 moles

7.40;14.8;29.6

Step-by-step explanation:

Step 1: Data given

Number of moles of magnesium perchlorate, Mg(ClO4)2 = 7.40 moles

Step 2: Calculate number of moles

In 1 mol of magnesium perchlorate, Mg(ClO4)2, we have:

1 Mol Magnesium (Mg)

2 moles of Chlorine (Cl)

8 moles of oxygen (O)

This means that for 1 mol of magnesium perchlorate, Mg(ClO4)2, we have the same amount of moles Magnesium (Mg), the double amount of moles of Chlorine (Cl) and 4x the amount of moles of oxygen (O)

Number of moles Magnesium (Mg)= 1 * 7.40 moles = 7.40 moles

Number of moles Chlorine (Cl) = 2 * 7.40 moles = 14.8 moles

Number of moles of oxygen atoms = 4 * 7.40 moles = 29.6 moles

7.40;14.8;29.6
