0.195g N2O x 2moles of N / 28g of N = 5.46 moles of N



2X14= 28g.

Step-by-step explanation:

As molar mass of
N_(2)O is 44.013 g/mol and it is given that its mass is 0.195 g.

Therefore, calculate its number of moles as follows.

No. of moles =
\frac{mass}{\text{molar mass}}

=
(0.195 g)/(44.013 g/mol)

= 0.0044 mol

Here, in 1 mole of
N_(2)O there is 2 mole of N. Thus, moles of N present in it is calculated as follows.


2 * 0.0044 mol

= 0.0088 mol

Thus, we can conclude that in 0.195 g of
N_(2)O there are 0.0088 mol of N.
