Answer 1

Answer #1

1 mole of Lead (Pb) consists of 6.023*10²³ atoms of Pb

We know that one mole of atoms is equal to Gram atomic weight of atom

ie one mole of Pb is equal to 207.2 g of Pb

0.495 moles of Pb is equal to how many grams of Pb

Weight of Pb = 0.495 moles *207.2 g/1 moles

= 102.564 grams

= 102.6 grams

Weight of 0.495 moles of Pb = 102.6 grams
