FREE Expert Solution

We’re being asked to determine the number of significant figures in 67,000 m2.


Every measurement or calculation we do with instruments in chemistry has some level of uncertainty called experimental error. Significant figures are necessary to communicate a level of accuracy and precision while dealing with this uncertainty.


Remember the rules in determining the number of significant figures:

1. If your number has a decimal point, start counting from left to right ().

 Start counting when you get your first non-zero number and keep counting until the end.
