5 g of hydrogen - x g of nitrogen
The mass of nitrogen in the second sample is 23.33 g.
5 g of hydrogen - x g of nitrogen
The mass of nitrogen in the second sample is 23.33 g.
This is a one-step unit analysis problem. Since we are staying in moles, grams of our compound, and thus molar mass, is not needed.
1 mole is equal to 6.022x10²³ particles as given, so:
2.49 mol
