Stoichiometry
« on: December 16, 2016, 09:59:16 PM »
The textbook answers:
25) a. 5.6 tonnes
      b. 9.93 tonnes

I've attached the questions and my working out for both questions to this post.

I don't know why but my calculations are not the same as the answer. They are a bit off by a few decimal points.

Multiplying by 1.1 and 1.05 is not a correct way of taking given percentages into account.

Try to derive the correct approach starting from the percentage definition.
