What is the mass of a mole of fluorine molecule?
Solution:
1 mole of fluorine molecule contains 6.022 × 1023molecules and weighs 38 g.
Therefore, mass of a fluorine molecule =g
how do we know what is the wieght of fluorine??????????????
= 6.31 × 1023g
Fluorine molecule is made up of 2 fluorine atoms. mass of 1 fluorine atom is 19. So the mass of fluorine molecule will be (19 x 2 = 38)
I mole of fluorine molecule = 38g. = 6.023 x 1023 molecules of Fluorine
