Hello,
I have this question on a pre lab that I am stuck on..
How many grams of fluorenone can 0.53 moles of sodium borohydride reduce?
That is all of the info that is gives. Is that enough to solve it? Confused??

How many moles of hydride does borohydride produce?
How many moles of hydride does fluorenone react with?
From there you should be able to work out the stoichiometry.

So BH4 has 4 and fluorenone will react with one?

so I did...
1 NaBH4 = 4 Fnone
0.53 x 4 = 2.12
2.12 x 180.192 (1 mol fnone) = 382.01 g
look right??

Sounds about right. 4 fluorenone to 1 borohydride.
