Answer:
The number of mol corresponding to 2,20 g Cl2 is 0,062.
Explanation:
As we know that the molar mass of chlorine is 35.45 g/mol and in this case we have 2.20 grams of gas, if we divide the mass of the chlorine over the molar mass we will have the moles of our compound.
moles = mass / molar mass
moles = 2,20 g / 35,45 g/mol
moles = 0,062
