Ken,

Interesting point. There are probably as many references to Avagadro as
Avogadro on the net and in textbooks but what we can agree on completely is
that it isn't avagardo and a man of such eminence; at the very least,
deserves his name to be spelt with a capital A.

I sincerely hope your instructor did not teach you "avagardos constant"

Hi,

So it's homework time is it?

Firstly you can't do it solely in Excel without reference to a table of
atomic weights and from that you should discover the following:-

Hydrogen atomic weight = 1.0079
Oxygen atomic weight = 15.994
Put these 2 values in A1(hydrogen) and A2(oxygen)
Now work out number of moles with this formula
=1000/(A1*2+A2)

To make it more flexible you could put the 1000gms in a cell and reference
it in the formula
=A3/(A1*2+A2)

But it's Avogadro.
