Question

How many oxygen atoms are in 2.71×10 power 25 molecules of CO2?
​

Answer 1

Step-by-step explanation:

FIrst Calculate the moles of CO2

2.71 × 10^2 ×1 mole CO2/6.022×10^23 molecules of CO2

=4.5 ×10^-14 Mole of CO2

1 Mole Of CO2 Has Two Moles Of Oxygen

=2×4.5 ×10^-14 Mole Of CO2

Therefore

9.0×10^-14

Hope This will help you

Answer 2

▪︎54.2 × 10²⁴ atoms of Oxygen are present.

1 molecule CO2 of and 2 molecule of O2 are present in molecules of CO2.

So, 54.2 × 10²⁴ atoms of Oxygen are present.
