Question

How many moles of n are in 0.195 g of n2o?

Answer 1

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



2X14= 28g.

Answer 2

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.
