Anybody know?

I am trying to to my homework.

Cheating on your homework, for shame!... [img]smile.gif[/img]

Good luck... [img]smile.gif[/img]

<font color="cyan">I'd try and learn basic English before you attempt chemistry!!

Lol, just kidding.

Erm, I'll read up on it, cos I used to know...so, I'll glance over some notes tomorrow and let you know cos it's been a few years, and I'm not sure on the EXACT procedure!</font>

There's a couple ways. Depends on the other info you have.

Molar mass? Does that have anything to do with teeth? [img]graemlins/laughsaywhat.gif[/img]

Chemistry song 13

O Come All Ye Gases

O Come all yea gases
diatomic wonders
O come yea, o come yea
calls Avogadro.

O come yea in moles
6 x 10 to the 23rd
O molar mass and molecules
O volume, pressure and temperature
O molar volume of gases at S.T.P.

God I hate chemistry

As someone said molar mass is a property calculated differently depending on the other known variables of the system. Is it a gas and do you know the partial pressure and volume? Is it a heterogen solution and do you know the concentration and volume? Is it a solid and do you know the mass?

Just molar mass is often only the values from the periodic system added together like for H20 2*1,008+16,00= 18,02g/mol for water

Oh, duh, I was thinking he was asking number of mols. [img]tongue.gif[/img] Yeah, you just add up the mass of each element in the compound.

Yeah, for the most part it's three-variable algebra. ax=b x=b/a a=b/x

Now, to find the Molar mass of a molecule, you add the Molar masses of each constituent atom...meaning that if there are two of any of them, you add it in twice, etc.

Single-element Molar masses are found on the periodic table...just look it up...chemists do ;)

Ask Dron Cah for more! He's a chemistry-oriented person...
