Answer to Question #185912 in General Chemistry for Gina Marcum

Question

For the reaction shown, calculate how many moles of NO2 form when each amount of reactant completely reacts.

2N2O5(g)->4NO2(g)+O2(g)

4.72×103molN2O5

Express your answer using three significant figures.

Answer 1

From the balanced equation

2mol of N₂O₅ gives 4moles of NO₂

Therefore,

4x10³moles of N₂O₅ will give 8x10³mol of NO₂
