Given :
Number of molecules of hydrogen peroxide, N = 4.5 × 10²².
To Find :
The mass of given molecules of hydrogen peroxide.
Solution :
We know, 1 mole of every compound contains Nₐ = 6.022 × 10²³ molecules.
So, number of moles of hydrogen peroxide is :
Now, mass of hydrogen peroxide is given as :
m = n × M.M
m = 0.0747 × 34 grams
m = 2.54 grams
Hence, this is the required solution.

2075g of XeF₆ is present in 8.46 moles of XeF₆
<u>Explanation:</u>
Given:
XeF₆ is xenon hexafluoride
number of moles of XeF₆ is 8.46
Mass of XeF₆ present, m = ?
We know,
Molecular weight of XeF₆, M is 245.28 g/mol
and
number of moles, n = mass of XeF₆ present / molecular weight of XeF6
Therefore, 2075g of XeF₆ is present in 8.46 moles of XeF₆
