2NO(g) + O2 (g) --> 2NO2

Question

How many grams of NO are required to react fully with 5.00 mol of O2?

I do not understand any of this please help

Answer 1

the reaction equation is written in MOLES

2 moles NO plus 1 mole O2 yields
... 2 moles NO2

so 5 moles of O2 uses 10 moles of NO

find the molar (formula) weight of NO, and multiply by 10
