Convert 8.50 grams Hg(NO3)2 to moles

I don't know

We will not do your homework for you, but will lead you through the process.

You need to determine the molecular weight from the formula first. Add up the total weight of the Hg, N, and O... making sure how many O's there are overall, and N's...

Do that and post what you get.

Once you do that you have the molecular weight in terms of grams/mole... the conversion to moles isn't tough... it involves cancelling out the grams... but again... determine the molecular weight first.

WOW. That is so easy. U must b in GP. I don't like helping dumb/lazy asses, but u mite b an honors kid who just is stressed out like me, so I'll show u what to do.


OK, so to do grams to moles, this is the process:

you use dimensional analysis

x moles= 8.5 g Hg(NO3)2 x 1 mole
molar mass Hg(NO3)2

u get molar mass by adding the average mass of all the elements in the compound, found on the periodic table
