Which gas is about zero point nine three percent of the atmosphere?
Answer and explanation
Correct answer: Argon
Argon makes up approximately 0.93% of dry atmospheric air by volume. It is a noble gas, so it is chemically unreactive under ordinary conditions. Therefore option B is correct. Nitrogen is about 78% and oxygen about 21%, so neither fits 0.93%. Ozone is present only in a very tiny, variable concentration, not nearly one percent.
