Diatomic oxygen is composed out of two oxygen atoms. Each oxygen atom has a molar weight of #16# # "g/mol"#, which means that the #O_2# molecule will have a molar weight of #2 * 16 = 32# #"g/mol"#.

One mole is defined as the weight of exactly #6.022 * 10^23# atoms or molecules, depending on the substance.

1 mole of #O# has #6.022 * 10^23# atoms of #O# and weighs 16 grams.
1 mole of #O_2# has #6.022 * 10^23# molecules of #O_2# and weights 32 grams.
