Question

How many moles of oxygen atoms do 1.5 moles of CO2 contain

Answer 1

Answer:

1 mole of co2 contain atoms of oxygen =2 ×6.02 ×10 ^23 atoms

1.5 moles of co2 contain atom of oxygen =2 ×6.02 ×10 ^23 atoms ×1.5 ÷1

=18.06 × 10 ^23 atoms of oxygen

Answer 2

Given:

1.5 moles of $CO_2$.

To Find:

Moles of oxygen atoms in 1.5 moles of $CO_2$.

Solution:

We know that a $CO_2$ molecule consists of 1 carbon atom and 2 oxygen atoms.

So, 1 mole of  $CO_2$ molecules will contain 1 mole of carbon atoms and 2 moles of oxygen atoms.

⇒ 1.5 moles of $CO_2$ molecule will contain 1.5 moles of carbon atoms and 3 moles of oxygen atoms.

Hence, the number of moles of oxygen in 1.5 moles of $CO_2$ = 3.
