Simple formula I use:. of Moles = Mass in grams divided by Molar Mass
=5o divided by (cl x 2)
=50 divided by 71
=0.704 moles
OR.
use: 1 mol = Mr in grams that is 35.5x2 g of Cl2 = 1 mol 71g of...
With only two atoms, the molecule can only be arranged in a linear form: Cl-ClThe angle is 180o and the molecule is symmetrical and therefore non-polar.
