  • About significant figures and precision

  • significant figures

     It refers to the number of digits in a number that has a rational basis as a measured value or analytical value, taking into account measurement accuracy, etc.

     If you write a concentration value in the answer column of an analytical chemistry test using an absurd (no rational basis) number of digits, such as 12.34567636455, you will be rejected immediately. Even if it is written in the experiment report, it is a considerable negative point.

     

    First, familiarize yourself with significant figures.
