How many atoms of lead are there in 25g of lead? Solve the question and show the steps
Accepted Answer
Steps:
1. Convert 25g of lead to grams
25g Pb * (1 mol Pb / 207.2 g/mol Pb) = 0.1206 mol Pb
2. Convert mols of lead to atoms of lead using Avogadro's Number (6.022 * 10^23 atoms/mol)
0.1206 mol Pb * (6.022 * 10^23 atoms Pb / mol Pb) = 7.26 * 10^22 atoms of Pb
