## MAS157 Mathematics for Chemists

 Semester 2, 2019/20 10 Credits Lecturer: Dr Alastair Williamson uses MOLE Timetable Reading List Outcomes Teaching Methods Assessment Full Syllabus

This module is designed for Chemistry Students. The module aims to reinforce students' previous knowledge and to develop new basic mathematical techniques needed to support the Chemistry subjects taken at levels 1 and 2.

(Note: this module and MAS154 are taught together.)

Prerequisites: A-level mathematics (or equivalent)

The following modules have this module as a prerequisite:

 MAS248 Mathematics III (Chemical)
