**Guidelines for Calculating Molar Mass of Lead(II) Bromide****Task**: Complete the table below to determine the molar mass of the ionic compound lead(II) bromide.### Table Details:| Formula | Molar Mass of Ion | Number of Ions | Mass of Ion in One Mole of Lead(II) Bromide ||---------|-------------------|----------------|-------------------------------------------|| **Cation** | Pb²⁺ | [____] g/mol | × [____] mol | = [____] g || **Anion** | Br⁻ | [____] g/mol | × [____] mol | = [____] g |### Calculation:- **Molar Mass Lead(II) Bromide** = [____] g/mol**Instructions**:1. Use reference materials to find the molar mass of the lead (Pb²⁺) and bromide (Br⁻) ions.2. Determine the number of each ion present in the compound.3. Compute the mass of each type of ion in one mole of lead(II) bromide by multiplying the molar mass of the ion by the number of ions.4. Sum up the mass of all ions to find the total molar mass of the compound.**Note**: This form is based on the assumption that the compound is PbBr₂, comprising one Pb²⁺ ion and two Br⁻ ions. Adjustments may be needed based on chemical formulas.

The compound given is Lead (II) bromide. From the name we can see that the compound has Lead (II) cation i.e Pb2+ and bromide anion i.e Br-. Since to balance the 2+ of Pb, 2 anions will be required. Hence the formula of ionic compound Lead(II) bromide will have 1 cation and 2 anion. Hence the formula is PbBr2. Because mass of electrons are negligible, hence the molar mass of ions will be almost same as that of the element atomic mass. => Molar mass of ion Pb2+ = atomic mass of Pb = 207.2 g/mol And molar mass of ion Br- = atomic mass of Br = 79.9 g/mol Since 1 mole of PbBr2 has 1 mol Pb2+ ion and 2 moles of Br-. Hence the molar mass of PbBr2 = molar mass of Pb2+ + molar mass of Br- X 2 = 207.2 + 79.9 X 2 = 367 g/mol approx. Hence the below table.
