Skills Worksheet Problem Solving Mole Concept Suppose you want to carry out a reaction that requires combining one atom of iron with one atom of sulfur. First, we construct the appropriate molar ratio The same two-step problem can also be worked out in a single line, rather than as two separate steps, as follows: We get exactly the same answer when.

CIE A Level Chemistry past paper exam questions organised by topic with mark schemes.
From a given number of moles of a substance, calculate Sometimes the answer may be slightly different from doing it one step at a time because of rounding of the intermediate answers, but the final answers should be effectively the same.
