If the atomic weight of nitrogen is 14.0, what is the mass of one mole of nitrogen gas (n2)?

14 grammes

Explanation:

if atomic weight of Nitrogen = 14 g/mole

mole =mass(g) / atomic weight(g/mole)

mass = 1moles x 14(g/mole)

mass = 14 grammes of Nitrogen

28.0.

Explanation:

Hello,

In this case, it seen that 1 only nitrogen weights 14.0 g/mol, in such a way, for diatomic nitrogen which is the most stable form of pure nitrogen has two nitrogens thereby the mass of one mole of nitrogen gas is 28.0g/mol because the aforementioned 14.0g/mol is multiplied by 2 accounting the two nitrogens.

Best regards.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

catya your not at all which answer i've seen you do this on another question!
