Question

Calculate numbers of atoms in 8.96 liters co2 at stp

Answer 1

Answer:

3.01 × 10²³  atoms.

Explanation:

We know that

In 1 mole of CO₂ = 22.4 L of CO₂.

Total numbers of atoms present in 1 mole = 6.022 × 10²³ atoms.

First let's find numbers of mole

Numbers of mole = Given volume / 22.4 L

Numbers of mole = 8.96 / 22.4

Numbers of mole = 0.4 moles.

Now ,

Total numbers of atoms present in 0.5 moles of CO₂ = 0.5 ×  

6.022 × 10²³ atoms.

Atoms present in 0.5 moles of CO₂ = 30.110 × 10²² atoms

Atoms present in 0.5 moles of CO₂ = 3.01 × 10²³  atoms.
