Question

Calculate the number of moles in 456 g of lead, Pb

Answer 1

Number of moles = 2.2 mol

Step-by-step explanation:

Given data:

Number of moles of lead = ?

Mass of lead = 456 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of lead = 207.1 g/mol

Now we will put the values in formula:

Number of moles = 456 g/ 207.1 g/mol

Number of moles = 2.2 mol
