Unit Conversion & Significant Figures: Crash Course Chemistry #2
 
11:24
A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international system of units. Hank thinks this is a thrilling subject, and while you may not agree, it is a subject that is very important if you want to be a scientist and communicate with accuracy and precision with other scientists. So listen up and learn something or Hank might have to kill you! (NOT REALLY!)

How many atoms in 5.5 moles? How many moles is 4.6 x 10^24 sulfur atoms? We'll solve problems like these, where we convert back and forth between moles and the number of atoms or molecules that we have. We'll be using both a common sense approach, and also a standard conversion factor method. We'll learn how to use a scientific calculation to do this math, and we'll see how to round our answers with scientific notation and significant figures.

Significant Figures | Add, Subtract, Multiply & Divide Sig Figs | Chemistry Physics Engineering

Understanding Significant Figures (also known as “sig figs”) is incredibly important in Science! When you collect data, whether you’re doing Chemistry, Biology, Physics, or Engineering, you need to notice how precise your tools allow you to be. There should be one estimated digit in your data. This is where the idea of significant figures comes from - from measurement! Make a note of how precise your data is before you start calculating. Then you round off to the correct number of significant digits at the end of your calculations. Otherwise, you give people the wrong idea of how precise your initial measurements were. In this video, we’ll go over all the rules for determining significant figures. We also do examples of sig figs in calculations! We show you the rules for adding, subtracting, multiplying, and dividing. We even cover the advanced topics of significant figures in logarithms and when you raise 10 to a power. ///////////////////////// You can click on the links below to jump to sections in the lesson: 0:29 Quick examples of significant figures 1:19 Where does the idea of sig figs come from? 2:30 RULE 1 2:54 RULE 2 4:22 RULE 3 4:58 RULE 4 6:40 Adding and Subtracting Significant Figures 7:30 Multiplying and Dividing Significant Figures 8:14 Logarithms and 10^x with Significant Figures 9:31 Super Useful TIP! ///////////////////////// What to watch Next: Unit Conversion 1: http://bit.ly/1YGOQgw Unit Conversion 2: http://bit.ly/1RGbwZ1 Scientific Notation: http://bit.ly/2cv6yTw ///////////////////////// Our Periodic Table app is FREE in the Google Play store! http://goo.gl/yg9mAF Don't miss our other chemistry videos: https://www.youtube.com/watch?v=aQw9G...
