Question

The mass of Carbon dioxide which contains 6.02*10^23 Oxygen atoms is?

Answer 1

Hey Friend ☺

we know that 1 mole of any gas has 6.022 × 10^23 atoms in it .

In carbon dioxide 1 mole of carbon combines with two moles of oxygen

Given that oxygen contains 6.022 × 10^23 atoms

means 0.5 moles of CO2 are present

mass of 1 mole of CO2 = 12 + 16 × 2

= 12 + 32

= 44

mass of Hal mole of CO2 = 44/2

= 22 u

so the mass of CO2 containing 6.022 × 10^23 oxygen atoms is 22 u
