Aims of this unit
This unit makes up part of the non-lab rotation of the course. Its aim is to build confidence and give you the opportunity to practise calculations and mathematical manipulations outside the laboratory environment.
You will have encountered many of these calculations in your previous studies; however we find that students often get confused, make mistakes, or lack confidence in these areas. These basic skills and calculations are crucial to successful synthetic and analytical work so it is important that you master these skills now at the beginning of your course.
Learning objectives
By the end of this unit you should be able to confidently and accurately:
- Plan a synthesis, including calculating masses, moles, volumes and concentrations.
- Determine the success of an experiment using percentage yields and percentage errors.
- Manipulate concentrations and volumes to calculate and express dilutions in a number of formats.
- Express errors and uncertainties in different forms and propagate errors through calculations.
- Plot straight line graphs and manipulate graphical data.
- Convert between units used in the laboratory, in particular those relating to light and energy.
Structure of this unit
This unit will run continuously throughout the first term. There are five parts to this unit and we expect you to complete one part every two weeks.
- Amount of substance
- Error analysis
- Graphical data
- Light and energy
- Unit conversions
Each section will consist of content in various formats, written information, activities and example questions with worked answers. The section finishes with a short summative quiz to test your understanding.
Assessment for this unit
This unit is worth 30% of the module mark.
At the end of each section there is a short summative test. Each test is worth 6% of the module mark.
You may attempt each test three times. Your highest mark will be taken forward to the calculation of the final module mark.
