The Ideal Gas Law - correct answer ✅ PV = nRT.
Tells you how a gas responds to a change in its physical conditions. change P, V or
T, and the others adjust
Stoichiometry - correct answer ✅that portion of chemistry dealing with
numerical relationships in chemical reactions; the calculation of quantities of
