Title: Other Expanded Road Map Example Problems
Course: Stoichiometry

The following are clips of other people solving extended stoichiometry problems. You may solve the problem their way, my way, or your own way!!! I have listed the problem statements before the video. Try each problem before viewing the video and the answer. Good luck!!!

Problem #1:

Given the following reaction:

N_2(g) + 3 H_2(g) ==> 2 NH_3(g)

If 11.2 L of N_2 reacts, how many L of NH_3 form?

(Note: it is not mentioned that this problem is at STP, but he solves the problem originally like it is at STP. He also shows you a method of solving the problem if it wasn't at STP.)

Video (problem starts at ~4:18 mark):

Problem #2:

Given the following reaction:

Zn + HCl ==> ZnCl_2 + H_2(g)

At STP, how many liters of H_2 are formed by reacting 38.2 g of Zn?

(Note: His sig figs are incorrect in the problem. He should report his answer to 3 sig figs only.)
