A. What is the ratio of molecules in 1 mole of NH3 and 1 mole of HNO3 .

Question

4. Solve problems :

A. What is the ratio of molecules in 1 mole of NH₃ and 1 mole of HNO_{3 .}

Answer 1

Correct answer is 1:1 

one mole of any substance,compound , or elements contain particles equal to avagadro's number i.e. 6.022$\times {10}^{23}$ 

$\therefore$ 1 mole of NH₃ =6.022$\times {10}^{23}$  molecules of NH₃

and 

1 mole of HNO₃ =6.022$\times {10}^{23}$  molecules of HNO₃ 

$\therefore Ratio=\frac{6.022\times {10}^{23}}{6.022\times {10}^{23}}$ 

therefore , the ratio of molecules of NH₃  and HNO₃ is 1:1
