Many problems in chemistry and other sciences are presented as word problems. Word problems are as easy to solve as numerical problems once you understand how to approach them.

### How to Solve Chemistry Word Problems

- Before you break out your calculator,
**read**the problem all the way through. Make sure you understand what the question is asking. - Write down all of the information you have been given. Keep in mind, you may be given more facts than you need to use in order to perform the calculation.

- Write down the equation or equations you need to use in order to solve the problem.
- Before you plug the numbers into the equations,
**check the units**required for the equations. You may need to perform unit conversions before you can apply the equations. - Once you are certain your units are in agreement, plug the numbers into the equation and get your answer.
- Ask yourself whether the answer seems reasonable. For example, if you are calculating the mass of a beaker and you end up with an answer in kilograms, you can be pretty certain you made an error in a conversion or calculation.
