Question

Calculate the number of 3 mol helium

Answer 1

To calculate the number of 3 mol of helium, we can use Avogadro's constant, which is approximately 6.022 x 10^23 particles per mole.

Number of helium atoms = Number of moles of helium x Avogadro's constant

Number of helium atoms = 3 mol x 6.022 x 10^23 atoms/mol

Number of helium atoms = 1.8066 x 10^24 atoms
