The accuracy of the answer is limited to the LEAST significant figures of the input. So if two measured quantities are multiplied or divided, one of which is accurate to only two significant figures, and other to six significant figures, the answer is only accurate to two significant figures. HOWEVER: use all the figures you have for the calculation, and then round your answer to two significant figures. Also, however, remember that if you are multiplying by an actual exact number, as in doubling, the significant figures of that 2 is unlimited, so the answer is only limited by the significant figures of the number you are doubling.
Two significant figures.
Two significant figures.
The number of significant figures depends on the the errors of measurement, the uncertainty of reported values, and the significant figures of table values. Ending zeros are only significant if necessary. For example, suppose I want the number of meters in a kilometer to four significant figures. In scientific notation this would be 1.000 * 103. In regular notation, it would be 1000. The period at the end is not for the end of the sentence, but rather to signify that all included digits represent significant digits with regard to accuracy.
There are two significant figures in 0.068.

Two of them.
All four figures are significant in 8,807.
all the zeros are significant. there are four significant figures.
All 3 of them.
Three. All nonzero digits are significant and zeros in between significant digits are always significant.

There are two significant figures which are the two 2s.
There are 4 significant figures in 0.0032. Seems to be only 2 significant figures in this number.
