Best ResponseYou've already chosen the best response.2First, make sure the equation is balanced. Next, can you find the number of moles of whatever substance you have? Use this: http://www.ptable.com/

Best ResponseYou've already chosen the best response.2I mean, write a balanced equation first.

Best ResponseYou've already chosen the best response.0So..\[N _{2}(g) + h _{2}(g) \rightarrow NH _{3}\]

Best ResponseYou've already chosen the best response.2Oh my the equation editor is not working for me but I can see it. From here can you just use normal typing? Notice that the equation is not balanced. You have 2 N on the left and one on the right. And you have 2 H on the left and 3 on the right.

Best ResponseYou've already chosen the best response.0so N2 + 3H2 = 2NH3

Best ResponseYou've already chosen the best response.2Right. So now, you know how much H2 you used. Can you fine the number of moles of it? http://erhs.rcsnc.org/UserFiles/Servers/Server_4766394/Image/Donna%20Scofield/mole%20conversion%20map.bmp

Best ResponseYou've already chosen the best response.2Sure. Do you know how to find the number of moles?

Best ResponseYou've already chosen the best response.0I know a mole is 6.02 * 10^23 thats about it

Best ResponseYou've already chosen the best response.2That is the Avogadro number  the number of objects in 1 mole of substance. But I'm sorry I misread the question. You are already given the number of moles. So here, from our balanced equation N2 + 3H2 = 2NH3 we can see that 3 parts of H2 produces 2 parts of NH3. What do you think we will do to get the moles of NH3?

Best ResponseYou've already chosen the best response.0Theres some formuala...

wolfe8

Best ResponseYou've already chosen the best response.2Nah. You have 24 mol which equals to 3 parts. Find for one part and multiple by 2 to get the mols of NH3

Best ResponseYou've already chosen the best response.0Can you show me, I feel so lost...

wolfe8

Best ResponseYou've already chosen the best response.2Sure. So 24 mol is equal to 3 parts of H2 we use based on the equation so we divide 24 by 3. Then we know we get 2 parts of NH3 from the equation so we multiply it by 2

Best ResponseYou've already chosen the best response.0so would it be 4 as the final answer?

Best ResponseYou've already chosen the best response.2Yeah. 4 mols. Do you understand what we did though?

Best ResponseYou've already chosen the best response.2NOOOOOO. 24/3 is 8 multiplied by 2 is 16

Best ResponseYou've already chosen the best response.0You know there is 24 mol. In 3 equal parts oh H2 and 2 equal parts of NH3?

Best ResponseYou've already chosen the best response.0Where do you get that information though? and oh okay just error in what comes first! sorry

Best ResponseYou've already chosen the best response.2Right. This is why we always need the balanced equation for stoichiometry.
