Modelová Otázka ID 3652 - 
Pro relativní atomovou hmotnost platí:
Správná odpověď je: B, C
Relativní atomová hmotnost je poměr skutečné hmotnosti atomu k atomové hmotnostní konstantě (1/12 skutečné hmotnosti atomu uhlíku 12C). Lze odvodit, že číselně odpovídá molární hmotnosti uváděné v g/mol, ale jedná se o dvě různé veličiny. Jelikož je relativní atomová hmotnost definována jako poměr dvou hmotností, jedná se o bezrozměrnou veličinu.
