mass of 8.39*10^23 molecules of flourine

Answer 1

To calculate the mass of 8.39*10^23 molecules of fluorine, we first need to find the molar mass of fluorine. The molar mass of fluorine is 18.998 g/mol.

1 mol of fluorine = 18.998 g
1 molecule of fluorine = 18.998 g/6.022*10^23 molecules
8.39*10^23 molecules of fluorine = (18.998 g/6.022*10^23 molecules) * 8.39*10^23 molecules

Simplifying the above expression:

8.39*10^23 molecules of fluorine = 26.74 g

Therefore, the mass of 8.39*10^23 molecules of fluorine is 26.74 g.
