What will a helium analyzer read for helium concentration when exposed to ambient room air?

Explanation:
A helium analyzer, when exposed to ambient room air, will read a concentration of 0% for helium. This is because room air primarily consists of nitrogen (around 78%) and oxygen (approximately 21%), with trace amounts of other gases, including argon and carbon dioxide. Helium is not a component of ambient air in significant quantities, so the readings from a helium analyzer will reflect that absence, indicating a concentration of 0%. Understanding the composition of air explains why helium, which is a noble gas and not naturally found in breathable air, will not show any presence under normal atmospheric conditions.
