How many moles of n ant in 0.233 g of n2o

0.0106 mol of N in 0.233g of N2O

Explanation:  

To solve this you find out how many mol of N2O you can multiply that by 2 to find the mol of N. There are 2 N for every one molecule of N2O.  

To do this, you can use the Atomic Mass Unit of the atoms to find the mol. 1 mol of hydrogen has weights 1 gram, hydrogen has a atomic mass unit of 1. Atomic mass unit short hand is amu.  

For molecules if you take the total of amu for each atom in the molecule and add them together you will have the weight of the molecule in amu.  

The amu can be converted into how many grams are in one mole.  

N is nitrogen which has an amu of 14.  

O is oxygen which has an amu 16  

2 * 14 + 16 = 44 amu  

1 mol of N2O is 44 grams.  

0.233g / 44 g / mol = .00530 mol of N2O  

There is 2 N in each mol of N2O which means that .00530 mol * 2 = 0.0106 mol of N  

There are 0.0106 mol of N in 0.233g of N2O
