Mixed Practice:

For questions 6-9, you may not have to use your entire flow chart. Decide where to start and end using your flow chart.



4NH3 + 5O2 → 4NO + 6H2O


MM NH3 = 17.04 g/mol; MM O2 = 32 g/mol; MM NO = 30.01 g/mol; MM H2O = 18.02 g/mol



In the above reaction, how many moles of NO are formed if 824 g of NH3 react?



27.5 mol
3510 mol
48.4 mol
774 mol

Given

Mass of NO - 824 g

Molar mass of NO - 30.01g/mol

No of moles of NO = Given mass/Molar mass

No of moles of NO = 824/30.01= 27.45 mole

Hence 27.5 moles of NO are formed!
