Question

how many atoms of carbon and oxygen are present in 1.5 mole of Co2
how many molecules and atoms of phosphorus are present in 0.1 mole of P4 molecules ​

Answer 1

Answer:

In the given formula, CO_{2}CO

2

there is one carbon atom and there are two oxygen atoms. So, in total there are three atoms.

Also, it is known that according to Avogadro's number in 1 mole there are 6.023 \times 10^{23}6.023×10

23

atoms.

So, calculate number of atoms in 1.5 mole as follows.

1.5 \times 3 \times 6.023 \times 10^{23}1.5×3×6.023×10

23

= 27.10 \times 10^{23}27.10×10

23

Hence, we can conclude that there are 27.10 \times 10^{23}27.10×10

23

atoms of each carbon and oxygen atom present in 1.5 mole of CO_{2}CO

2

.
