Question

Calculate the molecular mass of Pb(ClO2)4. Remember to include units

Answer 1

So,

To find the molecular mass of this compound, we multiply the mass of each element by the number of atoms of each element in the compound and then sum all these values.

First, remember:

The molar mass of Pb is 207.2g/mol

The molar mass of Cl is 35.45g/mol

The molar mass of O is 16g/mol

This is:

Now, if we sum:

The molecular mass of Pb(ClO2)4 is 477g.
