Homework Help: science(chem)

Posted by ~christina~ on Monday, October 8, 2007 at 10:54pm.

I was told before that it takes 2 mol of fluorene to be reduced by 1mol of sodium borohydride....

How many mg of fluorenone can 0.53 mol of sodium borohydride(NaBH4) reduce?

what I got...

0.53mol NaBH4 ( 2mol fluorenone/ 1mol NaBH4)(180.192g/1mol fluorenone)(1000mg/1g)= 19,1003.52mg of fluorenone

Is it just me or does this look really huge in terms of the mg...

well 0.53mol NaBH4 (37.83g/mol)(1000mg/1g)= 20,049.9mg ...used

I don't really know...

Help please..
