hello mate!!
Explanation:
Atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units. Hence, atomic mass of oxygen is 16 u means that one atom of oxygen is 16 times heavier than 1/12 of a carbon-12 atom. Atomic mass of oxygen is 16 means that mass of an oxygen atom is 16 u....
Promethium-151

Molecular Formula: Pm
Synonyms: Promethium-151 15766-03-7 Promethium, isotope of mass 151 151Pm(~151~Pm)Promethium More.
Molecular Weight: 150.92122 g/mol
In 1 Mole of CO2
there are 2×6.023×10power23 oxygen atoms
In 0.1 Moles of CO2, there are 0.2×6.023×
10power23= 1.2046×10
hope you understood ✌️✌️❤️ ❤️
