Molecular weight
editQuestion: why C4H10O4 molar mass is 122.12 g/mol ?
I found the same value in NIST https://webbook.nist.gov/cgi/cbook.cgi?ID=149-32-6
But C4=48.000,H10=10.078,O4=63.980 => 122.058 g/mol in total which is quite far from 122.12 g/mol. Weird. 2001:6B0:1:1041:19C6:6D31:551:BAFB (talk) 10:39, 28 November 2022 (UTC)
