Hi super smart people! I was just wondering, how do I find the significant figures of a pH solution? I know it has something to do with the number on the right of the decimal but thats all...

Significant figures is the amount of figures at total, excluding 0 IN FRONT of a number between 1 and 9... some examples could be:

0.00000000001       1 significant figure

0.000000000010     2 significant figures

1.09*10^(-4)           3 significant figures.

123                         3 significant figures.

123.0                      4 significant figures.
