Rf values are typically rounded to two significant figures, as this reflects the precision of the measurements involved in chromatography. However, in some cases, rounding to three significant figures may be appropriate if the experimental data supports that level of precision. Ultimately, consistency in reporting and the context of the analysis should guide the decision on how many significant figures to use.

The rounded value is 10. See also the links below. * * * * * However, there is no such thing as the correct number of significant figures (sf). SF depends on the context as well as the SF of the numbers used to compute the value.
How many significant figures in the value 3028.0?
Five significant figures.
What is the significant figures of the number of 23.400?
There are five significant figures in the given value. It is according to the rule of significant figures which say that zeros right to the decimal point are significant and all non zero digits are significant So , all the digits in the given value are significant figures i.e 5 significant figures.
How many significant figures are in the number 4.270000?
As trailing zeros after a decimal point are not normally written, for them to be written means they must have significance, so 4.270000 has 7 significant figures (it may have been rounded from 4.2699995 to 7 sig fig). 4.27 (the same value) would only have 3 sig fig.
