Answer:

Explanation:
Hello,
In this case, the undergoing chemical reaction is:

Thus, since lead (II) nitrate is in excess, we can directly compute the moles of lithium nitrate by applying the 1:2 molar ratio between them in the chemical reaction as well as the molar mass of Lithium Sulfate that is 110 g/mol for the stoichiometric shown below factor:

Finally, by using the Avogadro's number we are able to compute the molecules:

Best regards.
