What is the mass of each and which is greater?
1g H2 + ?N2 and 1g H2 + ?O2
I've balanced them to this point:
3H2 + N2 ===> 2NH3
2H2 + O2 ===> 2H2O
Help please, I am stuck on this step and cannot get any further.
Thanks,
PJ
Good! You've done the hard part. For the first reaction, you know that the ratio of H2 to N2 is 3 moles to 1 mole. So, calculate how many moles of H2 you have...then the amount of moles of N2 is 1/3 of the H2 moles. Then, once you know how many moles of N2...you can calculate its weight. Can you finish?
DanH-
Is this correct, I'm trying to follow here...
3H2 is (3)2.016g for a total of 6.048g, so would the nitrogen mass then be 0.672g?...if so, then what...
Is 18.83g the correct mass for the N2 in the first equation? [.672 moles of Nitrogen (28.02g N2/1mole N2)]=
18.83g N2
I'm trying...if this ir right I think I can get the other one.
Thanks,
PJ

You need to go back and read the answer by DanH. You must convert grams to mols BEFORE you multiply or divide anything. Molecules and atoms don't react by grams, they react by mols.
Hello! great idea of color of this siyte!
