BabaBlast [244]

0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.

<h3>Total atoms in a compound</h3>

Given the following parameters

  • Mass of  Cu2s = 32.8 grams

Get the number of moles

  • Moles = Mass/Molar mass

Moles = 32.8/159.16 g/mol

Moles of Cu2S = 0.240moles

Since 1 molecule of atom  = 6.02 * 10^23 molecules

Hence 0.206 moles will contain 0.206 moles x 6.022 × 10^23 atoms which is equivalent to 1.240 x 10^23 atoms.
