When dealing with the study of natural phenomena, a purely objective approach must be made by scientists. This is because natural phenomena exist, devoid of human feelings or emotions. There is no room for subjectivity as the natural occurrences do not vary based on human thoughts and perceptions; rather they exist on their own.

Therefore, every evidence collected by scientists should be objective and analysis should be made based on characteristics displayed and not from their previous experiences or personal point of view.

An atom of an element weighs 3.38× 10–23 g. What is the atomic mass of this element in atomic mass units?

Answer: The atomic mass of this element in atomic mass units is 20.3

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

Let atomic mass of element is X amu

$6.023\times 10^{23}$ atoms weigh = X amu

1 atom weigh = $\frac{X}{6.023\times 10^{23}}\times 1=3.38\times 10^{-23}amu$

$X=20.3amu$

Atomic mass of this element in atomic mass units is 20.3
