Question

When dealing with diatomic elements like oxygen, the atoms are not separate; they always come in pairs. Therefore, one mole of oxygen molecules would weigh _______ grams and not 16 grams

Answer 1

32 grams

Explanations:

What are diatomic elements?

Diatomic elements are elements that contain two atoms chemically bonded together.

When looking for the molar mass of a diatomic element, the number of atoms in the element is multiplied by the molar mass of the element.

For instance, oxygen is a diatomic element with the chemical symbol of O₂. This shows that the molar mass of oxygen will be given as:

`\begin{gathered} molar\text{ mass of O}_₂=2*16g\text{/mol} \\ molar\text{ mass of }O_2=32g\text{/}mol \end{gathered}`

This shows that one mole of oxygen molecules would weigh 32 grams and not 16 grams.
