Question

How many moles of N are in 0.241 g of N2O?

Answer 1

0.00547 moles of N.

Answer 2

Step-by-step explanation:

Calculate the molar mass of the
`N_(2)O`:

Molar mass N =
`14(g)/(mol)`

Molar mass O =
`16(g)/(mol)`

Molar mass
`N_(2)O` = 2*(Molar mass of N) + Molar mass of O

Molar mass
`N_(2)O` =
`2*(14(g)/(mol))+16(g)/(mol)`

Molar mass
`N_(2)O` =
`44(g)/(mol)`

Calculate the number of moles of N in 0.241g of
`N_(2)O`:

`0.241gN_(2)O*(1molN_(2)O)/(44gN_(2)O)*(2molesN)/(1molN_(2)O)=0.01molesN`
