Question

Match the following elements along with their atomic masses.

• A. 14 u
• B. 1 u
• C. 16 u
• D. 12 u

Answer 1

Atomic mass of an element is the total mass of its atom and is measured in atomic mass unit (amu).

1 amu = $\frac{1}{12}$ x atomic mass of C-12

The table below lists the given elements along with their atomic masses.

$$\begin{array}{cc}\text{Element}& \text{Atomic Mass}\\ \text{Hydrogen}& \text{1 u}\\ \text{Oxygen}& \text{16 u}\\ \text{Nitrogen}& \text{14 u}\\ \text{Carbon}& \text{12 u}\end{array}$$ <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->
