Question

What is the ratio of nitrogen and hydrogen in ammonia?

Answer 1

Step 1: Identifying the elements

Ammonia is represented as $\left({\mathrm{NH}}_3\right)$

The atomic mass of nitrogen is 14u

The atomic mass of hydrogen is 1u

Step 2: Calculating the ratio

The ratio of nitrogen and hydrogen in Ammonia = $\frac{\mathrm{amu}\mathrm{of}\mathrm{N}}{(\mathrm{amu}\mathrm{of}\mathrm{H})\mathrm{x}3}=\frac{14}{3}$

Step 3: Conclusion

In Ammonia, nitrogen and hydrogen always combine in the ratio of 14:3 by mass.
