Calculate the mass of 3.011310*10²³ atom of nitrogen(Atomic mass of N=14u)

Open in App

Solution

Dear student!
We know that,
6.022 x 10 ²³ atoms of Nitrogen gas (diatomic gas) = 1 mole
So, 3.011 x10 ²³ molecules of nitrogen gas =( 1/ 6.022 x10²³ ) x 3.011 x 10²³ = 0.5 moles
Mass = number of moles $\times$ molar mass
= 0.5 $\times$ 14
= 7 g
