Significant figures
  • 2 answers

Mr. Thakur 7 years, 5 months ago

In significant figure are meaningful digits which are known with certainty. The uncertainty is indicated by writing the certain digits and the last uncertain digits and the last uncertain digits. Thus, if we write a result as 11.2mL, we say the 11 is certain and 2 is uncertainty would be +-11 in the last digit. Unless otherwise stated, an uncertainty of +1 in the last digit is always understood.
The meaningful digits which are known with certainty are known as significant figures.
