To calculate the number of moles of lead, we need to divide the mass of the lead by its molar mass. The molar mass of lead is 207.2 g/mol. Therefore, the number of moles of lead in a 442-gram lead anvil is:

moles of lead = 442 g ÷ 207.2 g/mol = 2.13 moles

The answer is choice B, which is 2.13 moles.
