Question

4. Solve problems :
A. What is the ratio of molecules in 1 mole
of NH, and 1 mole of HNO,
(Ans. : 1:1)​

Answer 1

Answer : The ratio of molecules of 1 mole of $NH_3$ and 1 mole of $HNO_3$ is 1 : 1.

Explanation :

First we have to calculate the number of molecules of $NH_3$ and $HNO_3$.

As we know that, 1 mole of substance contains $6.022\times 10^{23}$ of substance. That means,

1 mole of $NH_3$ contains $6.022\times 10^{23}$ molecules of $NH_3$

and,

1 mole of $HNO_3$ contains $6.022\times 10^{23}$ molecules of $HNO_3$

Now we have to calculate the ratio of molecules of 1 mole of $NH_3$ and 1 mole of $HNO_3$.

$\frac{NH_3}{HNO_3}=\frac{6.022\times 10^{23}}{6.022\times 10^{23}}=\frac{1}{1}$

Therefore, the ratio of molecules of 1 mole of $NH_3$ and 1 mole of $HNO_3$ is 1 : 1.
