Measurements in Chemistry, metric units, SI units, Unit factor Conversion, Significant figures, Energy, Density, Specific gravity

Dr. Walt Volland revised September 8, 2009

These are suggested problems for practice. There are many problems at the end of the chapters. You may not be able to do all of them. It is important that you work out answers and review them.

Answering a question only once is like shooting a free throw once for practice. Quiz questions will come from these and the exercises in the lecture notes.

These are for the 6th edition of McMurray. 2009
