What is the mass in grams of 2.6 x 1022 chlorine atoms?

The mass in grams of 2.6 x 10²² chlorine atoms is 1.53grams.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles by its molar mass as follows: Mass of a substance = no. of moles × molar massHowever, the number of moles of chlorine needs to be calculated by dividing the number of atoms by Avogadro's number:no. of moles = 2.6 x 10²² ÷ 6.02 × 10²³no. of moles = 0.432 × 10²² - ²³no. of moles = 0.432 × 10-¹no. of moles = 0.0432 molesMolar mass of Chlorine atom = 35.5g/molMass of chlorine = 0.0432 × 35.5mass of Chlorine atom = 1.53grams.

Therefore, the mass in grams of 2.6 x 10²² chlorine atoms is 1.53grams.
