Best ResponseYou've already chosen the best response.0\[2.00 \times 10^{23} molecules F _{2} \times \frac{ 1mol F _{2} }{ 6.023 \times 10^{23} molecules F _{2} } \times \frac{ 38.00 g F _{2} }{ 1mol F _{2} }\]

Best ResponseYou've already chosen the best response.01molF2, would that be the atomic mass or Fluorine times 2?

Best ResponseYou've already chosen the best response.0It should be way way less. The grams should be less than 38 grams.

Best ResponseYou've already chosen the best response.0on my calculator I typed in 2.00*10^23 x 37.996/6.022*10^23 x 38.00/37.996 = 1.26203919*10^47

Best ResponseYou've already chosen the best response.0Where are you getting those numbers? Use my dimensional analysis. As you can see the given unit is canceled out and the mass unit (grams) is left. No need to add anything.

Best ResponseYou've already chosen the best response.0I did use it. I replace 1molF2 w/ 37.996, thats the only thing that is different!

Best ResponseYou've already chosen the best response.0I got that by doing: (2*18.998) = 37.996

Best ResponseYou've already chosen the best response.0Close enough to be 38.00 gram. Thats why I put it on top of mole. 1 mole F2=38.00 grams F2 You dont replace anything in this conversion. You can but its not necessary. Just makes everything longer. And you are not entering it in the calculator right because of the unnecessary steps. (2.00 x 10^23/6.023 x 10^23) x 38.00 This is just basic operations.
