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

Explanation:

As molar mass of 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 =

                                    =

                                    = 0.0044 mol

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

                                 = 0.0088 mol

Thus, we can conclude that in 0.195 g of there are 0.0088 mol of N.

yes it is balanced
