Question

number of atoms present in 4g of h2o2​

Answer 1

Answer:

~2.834 × 10^23 atoms

Explanation:

Molar mass of H2O2 is = 34 g

Given mass of H2O2 is = 4 g

Therefore, no. of moles present in 4 g H2O2 = 4/34

By mole concept

We know that 1 mole of H2O2 contains = 6.023 × 10^23 molecules of H2O2

therefore, 4/34 moles of H2O2 contain = 4/34 × 6.023 × 10^23 molecules of H2O2

Now, 1 molecule of H2O2 contains = 4 atoms ( 2 oxygen and 2 hydrogen )

Therefore, 4/34 × 6.023 × 10^23 molecules contain = 4/34 × 6.023 × 10^23 ×4 atoms

which comes out to be

~2.834 × 10^23 atoms
