Calculation of Number of Atoms in 52 g of Helium
Given:
Mass of helium (m) = 52 g
Gram atomic mass of helium (M) = 4 g
We know that the number of atoms present in a sample can be calculated by using the following formula:
Number of atoms = (mass of sample / gram atomic mass) x Avogadro's number
where Avogadro's number (NA) is a constant with a value of 6.022 x 10^23 atoms/mol.
Using the above formula, we can calculate the number of atoms present in 52 g of helium as follows:
Number of atoms = (52 g / 4 g) x 6.022 x 10^23 atoms/mol
Number of atoms = 13 x 6.022 x 10^23 atoms
Number of atoms = 7.83 x 10^24 atoms
Therefore, the correct answer is option C, which states that there are 13 times Avogadro's number of atoms present in 52 g of helium.
