Laughing gas (nitrous oxide, N20) is some- times used as an anesthetic in dentistry. It is
produced when ammonium nitrate is decom-
posed according to the reaction
NH4NO3(s) — N2O(g) + 2 H2O(l).
How much NH4NO3 is required to produce
46.4 g of N2O?
Answer in units of g.

109.2g

Explanation:

1 mole N2O = 34 g

46.4g = 46.4/34 moles = 1.365 moles

1 mole N2O is from 1 mole NH4NO3

1.365 moles NH4NO3 = 1.365*80g = 109.2g

well off of my head we know that the perfume bottle is most likely opened, or broken. i can also tell it is moving at low and high concentration because it is covering the other side of the room. what we can obtain from this information is it explains why the odor can be detected at the other side of the room.
