Aug 24, 2015 · Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, O and O. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant). In addition, 120.00 has five significant figures since it has three trailing zeros. for calcium hydroxide is 6.5 × 10 –6, so calculate a rough value of the concentration of OH – ion, [OH –], in the saturated solution (see prelab question on WebAssign; to two significant figures).
