Answer :
The atoms of helium are required to equalize the mass of a silver atom is 8.4 x 10 ⁻⁴⁸.
What are atoms?
Atoms are the minute particles that are present inside elements.
Atomic mass of silver is 107.86 g/mol
Mass of one atom of silver will be
[tex]\dfrac{ 107.86 }{6.022 \times 10^{-23}} = 1.79 \times 10^2^4[/tex]
Atomic mass of helium is 6.941
[tex]\dfrac{6.022 \times 10^{-23}}{4.0 \times 1.79 \times 10^2^4 } = 8.4 \times 10^{-48}[/tex]
Thus, the atoms of helium are required to equalize the mass of a silver atom is 8.4 x 10 ⁻⁴⁸.
