Are my answers to these Chemistry problems correct?

Question

*The scientist who discovered the relationship between the relative volume of a gas and the stoichiometric coefficients in a chemical equation was _______.

A. Avogadro

B. Boyle

C. Dalton

D. Gay-Lussac

E. None of the Above

*The stoichiometric coefficients in a chemical equation not only relate to the relative gas volumes involved, but they also indicate the _______ of the gases involved.

A. number of moles

B. number of grams

C. weight

D. density

E. None of the Above

Answer 1

I believe the answer to the first question would be (A) Avogadro because Gay-Lussac's law says that the pressure of a given mass varies directly with the temperature when the volume is constant.

I agree with your second answer.
