The mass of a single chloride (Cl) atom can be calculated by using its molar mass. The molar mass of Cl is given as 35.45 g/mol, which means that one mole of chlorine atoms (approximately 6.022 x 1023 atoms) weighs 35.45 grams.
To find the mass of a single Cl atom, you can use the following formula:
Mass of one atom = Molar mass / Avogadro’s number
Substituting the values:
Mass of one Cl atom = 35.45 g/mol ÷ 6.022 x 1023 atoms/mol
Calculating this, we find:
Mass of one Cl atom ≈ 5.88 x 10-23 grams.
Therefore, the mass of a single chloride atom is approximately 5.88 x 10-23 grams.
