What is the mass of 4.67x10^23 atoms of lead
To calculate the mass of 4.67x10^23 atoms of lead, we first need to determine the molar mass of lead.
The molar mass of lead (Pb) is approximately 207.2 g/mol.
Now, we will use this molar mass to calculate the mass of 4.67x10^23 atoms of lead:
1. Calculate the number of moles in 4.67x10^23 atoms of lead:
Number of moles = Number of atoms / Avogadro's number
Number of moles = 4.67x10^23 / 6.022x10^23
Number of moles ≈ 0.775 moles
2. Calculate the mass of lead:
Mass = Number of moles x Molar mass
Mass = 0.775 moles x 207.2 g/mol
Mass ≈ 160 g
Therefore, the mass of 4.67x10^23 atoms of lead is approximately 160 grams.
