Question in CHY1200 General Chemistry
A simple ideal gas law question, using number of molecules, that asks the student to calculate one of the four variables. he question can ask for either L atm, or kPa m3, and either K or C for temp. As such the boltzmann constant is in either J/K or L atm/K.

Question in Gilas Review (Grade 6)
Given percentages of males and females working on a project, and the percentage of the total staff who are male (or female), find the percentage of all staff working on the project.
Based on question 3 from section 3 of the mathsaid workbook on numerical reasoning.

Question in Christian's workspace
A quick implementation of certaintybased marking: the student's score depends on how they rated their certainty in their answer before submission.
Because Numbas doesn't allow negative marking at the moment, scores are shifted upwards, so a high certainty incorrect answer scores 0, and a high certainty correct answer scores full credit.

Question in Jane's workspace
Solving a three phase system

Question in CHY1201  SpectroscopyThe reduced masses are precalculated for this question and included in a list. It would be more elegant to program Numbas to permute atoms together to generate diatomic molecules while constraining the permutations to those which are chemically/physically reasonable, so as to allow calculation of each reduced mass directly from the atomic masses but organising this with high computational efficiency might be a significant programing task (add to "to do" list).
