The reaction is O3 + NO arrow O2 + NO2

If 0.740 g O3 reacts w/ 0.670g of NO, how many grams of NO2 will be produced?

I've tried to solve this.

but I can't seem to get the right answer

Here is an example I have posted to show how to work stoichiometry problems. It isn't your problem but most stoichiometry problems are alike. Here is a hot link.
