Answer:

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

PubChem CID: 177678

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 ✌️✌️❤️ ❤️
