How many total atoms are in 0.230 g of p2o5

Molar mass P₂O₅ = 141.9445 g/mol

141.9445 g 6.02 x 10²³ molecules
0.230 g  ?

molecules = 0.230 * 6.02 x 10²³ / 141.9445

molecules = 1.3846 x 10²³ / 141.9445

= 9.75 x 10²⁰ / 141.9445

= 6.868 x 10¹⁸ molecules of P₂O₅

calculation of the total number of atoms

P₂O₅ = 2 atoms of P and 5 atoms of O = 2 + 5 = 7

1 molecule P₂O₅ 7 atoms
 6.868 x 10¹⁸ molecules ?

atoms = 6.868 x 10¹⁸ * 7 / 1

= 4.807 x 10¹⁹ atoms

hope this helps!
