Question

calculate the mass of the 6.022×10²³ number of o2 molecules ( mass form number) with full calculation. ​

Answer 1

16 g

Explanation:

Avogadro's number (NA) = 6.022×10²³, molecular mass of Oxygen = 16

According to Avogadro's law,

The molecular weight of any substance has the number of molecules = Avogadro's number (NA)

∴ the mass of the 6.022×10²³ number of o2 molecules will be 16 g.
