Answer:

207g/mol

Explanation:

Given parameters:

Mass of the lead  = 41.4g

Number of moles  = 0.2mole

Unknown:

Molar mass of lead = ?

Solution:

The molar mass of substance is related to mass and number of moles using the expression below;

           Mass = number of moles x molar mass

        Molar mass = [tex]\frac{mass}{number of moles }[/tex]

Now insert the parameters and find the molar mass;

     Molar mass = [tex]\frac{41.4}{0.2}[/tex]   = 207g/mol
