Question

calculate the molar mass of argon atoms given that the mass of single atom is 6.634×10-26 kg

Answer 1

Hey there !

Solution:

1 atom = 6.634 × 10⁻²⁶ Kg

=> Argon has 6.023 × 10²³ atoms in one mole

=> Molar Mass = Mass of Single Atom × Number of atoms

=> Molar Mass = 6.634 × 10⁻²⁶ × 6.023 × 10²³ Kg

=> Molar Mass = 6.634 × 6.023 × 10⁻³ Kg

=> Molar Mass = 39.925 × 10⁻³ Kg

=> Molar Mass = 39.925 g

Hope my answer helped !
