# WT Virtual Math Lab - Math Help for Chemistry

Math Help for Chemistry

WTAMU > Virtual Math Lab > Math for Sciences

Introduction

This page is a work in progress. We are planning to add to and improve the content. Feel free to use what we have so far.

If you need help with the math part of chemistry, you have come to the right place.  Note that this will not help you with direct chemistry topics, but will help you with the math required to solve various chemistry problems.  Note that you do not have to be a student at WTAMU to use this math in chemistry help session.  It was created as a service to anyone who needs help with the math part of chemistry.

HOW TO EFFECTIVELY USE THIS WEBPAGE:

There are nine main math concepts shown below. These represent some of the common types of math problems that show up in various chemistry courses. You can pick and choose which math topics go with your particular chemistry problems.

Under each specific concept, you will find links to in-depth tutorials that will help you to learn and review the material.  These tutorials come from the WTAMU Virtual Math Lab, which I created.  Within these tutorials, you will find pertinent definitions, formulas, step-by-step explanations, an answer/discussion section with step-by-step solutions, and links to other credible webpages that can help you further with that topic.

In math, when you study a specific topic, a lot of times you are incorporating other mathematical topics into solving the problem.  Some of the tutorials will overlap each other.  This will help reinforce the concepts you need to know to do math in your chemistry class. Under some categories, there is overlapping between the different levels (beginning, intermediate, and college) of tutorials.  Find the algebra level that agrees with you most and do the tutorials under that level.  If you start below college level algebra, make sure that you make your way up through college algebra.

The math part of chemistry at this website is split into nine main areas:

*Note that not every math concept for chemistry is shown here, but we do plan to add some more topics at a later date.

Basic Mathematical Computations

This area contains basic math concepts.  You know, fun things like making sure you have the negative in the right place and remembering when you have to find the common denominator of your fractions.  Don't worry, I have the utmost confidence that you will do much better with arithmetic than Calvin.

Beginning Algebra Tutorial 3: Fractions

This tutorial covers:
• numerators and denominators of a fraction
• the prime factorization of a number
• simplifying a fraction
• finding the least common denominator of given fractions

Averages

This area contains help in finding central tendencies. Sometimes in chemistry you need to be able to find an average or mean which is one of the central tendencies.

Beginning Algebra Tutorial 34: Central Tendencies

This tutorial covers:
• finding the mean, median, mode, range, standard deviation and frequency distribution of a list of values

Exponents and Scientific Notation

This area contains help in working with exponents and applying that to scientific notation problems.

You will find several levels (beginning, intermediate and college pre-req) of help in exponents. There will be some overlapping between the levels.  If a topic has tutorials in more than one level, try going under the highest level first.  If that is too hard for you, go to the tutorials of the next level down, if available.  If that is too hard for you, go to the tutorials of the next level down, if available.

Once you find a level to start with, make sure that if it is below college level, in the end you work your way up to college algebra.

The beauty of this is it is individualized.  You can go at your own pace at the comfort of your own computer.  You know better than anyone else what your algebra skills are.
