How many moles of N are in 0.201 g of N 2 O?

The number of mole of N in N2O is 0.00914mol

Explanation:

First, we calculate the molar mass of the compound N2O

N - 14.0067

O - 15.999

Mm of N2O = 2 * 14.0067 + 15.999

= 44.0124g/mol

Then, we calculate the number of mole of N2O

Using this formula

n = number of mole

m = number of mass

Mm = molar mass

n = 0.201g / 44.0124g/mol

= 0.00457mol

Since there are two moles of nitrogen in each mole of the compound N2O

= 0.00457mol * 2

= 0.00914mol of N
