Calculate the number of atoms per cubic meter in lead. The density and atomic weight of lead are 11.35 g/cm3 and 207.2 g/mol respectively. The value of Avogadro's number is 6.022 x 1023 atoms/mol.

Number of lead atoms per cubic meter

Explanation:

Density of lead is means mass of lead is 11.35 g

11.35 g of lead = of lead = 0.05478 mol of lead

number of particles

So, 0.05478 mol of lead = number of atoms of lead

                                       = number of atoms of lead

So, number of lead atoms per cubic meter =

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
