What are the significant numbers in 10.00?
In 10.00, the first significant figure is the "1", and the last significant figure is the last "0", because zeroes to the right of the decimal are significant. The two central zeroes are also significant because they are between significant figures, so 10.00 has 4 significant figures.
When determining the number of significant digits in a measurement all zero are significant?
If your question was 'what is 216 to one significant figure', the answer would be 2. This is because the two means two hundred. If your number was 0.216 and you had to round it to one significant figure it would also be 2, but if your number is 0.203 and you had to round it to two significant figures you would say 20 this is because you only count the zeros as significant figures after an actual number. For example; 0.31 to two significant figures would be 31 but 0.301 to two significant figures would be 30.
