Answer:

8759g

Step-by-step explanation:

Given parameters:

Number of moles = 19moles

Unknown:

Mass of PbI₂ = ?

Solution:

To solve this problem, we first find the molar mass of PbI₂;

Molar mass of PbI₂ = 207.2 + 2(126.9) = 461g/mol

Mass of PbI₂ = number of moles x molar mass = 19 x 461

= 8759g
