The molar mass of Cl is 35.45 g/mol. What is the mass of the chloride atom in grams.?
There are 6.02E23 atoms in a mol; therefore, 35.45/6.02E23 = mass of 1 atom Cl.
To find the mass of the chloride atom in grams, we need to use the molar mass given.
The molar mass of Cl is given as 35.45 g/mol. This means that one mole of chlorine atoms has a mass of 35.45 grams.
However, we need to find the mass of a single chloride atom, not a mole of atoms. To do this, we need to convert the molar mass to the mass of a single atom.
To convert from moles to atoms, we can use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole.
So, we can calculate the mass of a single chloride atom as follows:
Mass of a single chloride atom (in grams) = (Molar mass of Cl) / (Avogadro's number)
Mass of a single chloride atom (in grams) = 35.45 g / (6.022 x 10^23 atoms/mol)
Calculating this value:
Mass of a single chloride atom (in grams) ≈ 5.89 x 10^-23 g
Therefore, the mass of a single chloride atom is approximately 5.89 x 10^-23 grams.
