Question

Use the balanced equation, N2 + O2 --> 2NO, to answer the following questions...

A) How many grams of NO are formed from 10.0g of N2?

I really don't know how to do this, so please show work so i know. There are more questions to this question but i want to see how it works.

Answer 1

N2 + O2 --> 2NO

mols N2 = grams/molar mass = 10/28 = approx 0.3 but you need a more accurate answer than that estimate.

Use the balanced equation to convert mols N2 to mols NO. That's 0.3 x (2 mols NO/1 mol N2) = approx 0.3 x 2/1 = approx 0.6 mol NO.

Then grams NO = mols NO x molar mass NO = ?

Answer 2

Thanks for the help! I around my answer to 4 sig figs, so my answer is 21.4 g of NO. thanks for the help again!

Answer 3

I meant 3 sig figs.
