In another experiment, a small piece of Mg(s) is weighed, then placed in a flask
containing excess 1 M HCl(aq). The student wants to determine number of
moles of gas produced. Which of the following is the best way to conduct the
experiment for accurate data collection?
(A) Conducting the experiment at different temperatures to see which generates
the most gas
(B) Completing the entire reaction in a large Erlenmeyer flask of known
volume to measure the volume of the gas collected
(C) Collecting the gas in a eudiometer tube and measuring the volume of the
gas collected
(D) Conducting the reaction in a graduated cylinder and measuring the volume
of the gas collected
