Thread: Need chemistry help!!! = (

Grumble Grumble Grumble

And you want to be given the answers to such simple chemistry problems????

(The trick to these kinds of questions is to simply count whats going in, vs. what is coming out..)

as an example 1 mole of O2 contains 2 moles of O

so as your asked question, it would make a difference if it was Mg2 vs. 2 x Mg, the number of atoms of Mg are the same, but the number of molecules are different...

Anyway, to quote the Forum Rules...

im completely lost when it comes to stoichiometry.

Chemistry is my worst subject, im way better at phiysics, and i like it alot more, but my counselor denied me physics and stuck me with chemistry instead, which im still furious about >= (

i already had the class but nooo!

anyway, thanks for the help mr. miyata! (^o^)

but im still cunfuzzled.

And by the way, the answers are..

1. 4
2. 14 x (weight of a mole of oxygen)
3. 24

Try to understand how these answers were derived...
