Homework Help: chemistry (drbob222)

Posted by Anonymous on Sunday, October 4, 2009 at 9:00pm.

I posted yesterday. Re: Chemistry (Sunday, October 4, 2009 at 12:49pm). Here's the information I left out.

Number 3 simply states: nickel forms a large number of ammonia salts Ni^2+(NH3)m(Br)n . p(H2O) where m, n, and p represent the coefficients in the formula

How do you know how many molecules ammonia has? (why did you say 2? –are you doing a trial and error?) How do you know to subtract Ni and 2NH3 and divide by the molar mass of H2O? Is there some kind of formula? (I tried searching online, but haven’t had any luck) How would I mention Bromine in the molecular formula? Like this: Ni^2+(NH3)2(Br)0 (H2O)4 ? Sorry for asking so much questions. Thank you so much for the help!
