Problem

How many significant figures are in the measurement, 0.0005890 g?

A. 4
B. 5
C. 6
D. 7
E. 8

Solution

We are asked to identify how many significant figures are in 0.0005890 g


Follow the 2 rules below to identify the number of significant figures. 

1. If your number has a decimal point move from Left to right (→)

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

2. If your number has NO decimal point move from Right to Left (←)

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