Chemistry can be a very exciting. You can mix substances, new things, change the color of the products, create odors and go BANG! The chemistry is the backbone of pharmaceutical research, detective work and the development of the CIS food. So the chemistry very attractive for many students to recognize them, must have some math skills.
But do not panic, your math skills, the basic chemistry needed, very simple and can be mastered by one. So here's a list ofthe most commonly used math skills in chemistry.
Scientific notation
Scientific notation is a very useful tool. It allows chemists to write very large and very small numbers easier. It involves the use of orders of magnitude the number of digits that you need to write, is lower.
10, 000 1 x 10 ^ 4
1 is 0.0001 x 10 ^ -4 Significant figures (figs SIG)
Significant figures (sig figs) help the chemical integrity of your data. The calculations are only as good as theThe collected data. The data is only as good as the tools used and the tool is only as good as the person using it. If the instrument measures only one-tenth of a unit, can not be your best accuracy of the instrument. Understand how important people work preserves data integrity.
Fractions
Many calculations in chemistry require the ability to manipulate, fractions. You need to understand how to reduce fractions and common fractions significantlyDenominator.
Decimals
The ability to work with decimals is very important, because most chemical measurements are not exact. Many of your measures will be part of things (fractions) and it is best to use the numbers as decimal fractions in the description of the data. You need to have values you know and how to convert fractions to decimals.
Percentages
It 'important to understand percentages in chemistry, because often, the data will be converted to a percentage ofComparisons. Percentages are not very difficult to understand. The percentages are just another way of writing fractions and decimals. Example: 1 / 2 =. 50 = 50%
Pre-Algebra
Most problems require only simple chemical pre-algebra skills. If you can solve simple equations and basic scheme of a coordinate system, then your algebra skills are sufficient. No need to pre-calculus or calculus.
Computer
For the chemistry even easier, you should invest in a TI-84Graphing calculator. The time and headaches, which are resolved by learning to use a computer is well worth the investment. A TI-84 not only the usual arithmetic, but it may help to sort and graph the data.
