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 mass
- However, 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 × 10²³
- no. of moles = 0.432 × 10²² - ²³
- no. of moles = 0.432 × 10-¹
- no. of moles = 0.0432 moles
- Molar mass of Chlorine atom = 35.5g/mol
- Mass of chlorine = 0.0432 × 35.5
- mass of Chlorine atom = 1.53grams.
Therefore, the mass in grams of 2.6 x 10²² chlorine atoms is 1.53grams.
