The measurement 0.02507 g should be reported as 0.0251 g.
It depends on the characteristics of the preparations being compared. If they are both standardized and follow a similar protocol, then the measurements should be comparable. However, if there are significant differences in the preparations or protocols used, the measurements may not be directly comparable.
You should convert metric measurements to standard US measurements when you need to communicate with someone who is more familiar with the US system, or if the specific context or requirements you are dealing with call for the use of standard US measurements.
The number of significant figures in a measurement is determined by the precision of the measuring instrument. Include all certain digits plus one uncertain digit (estimated or interpolated). Nonzero digits, zeros between nonzero digits, and trailing zeros in numbers containing a decimal point are considered significant.
There are 3. The final zero, if not significant, should not be there and so it must be significant.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Out of all the measurements used in the calculation, find the one with the least number of significant digits. This will be the limiting factor of how many significant digits the answer should have.
The measurement 0.02507 g should be reported as 0.0251 g.
A ruler or scale should not be read to less than the smallest graduation. In practice, in-between measurements can be estimated but they are not significant.
Yes, the precision of an answer depends on the precision of the measurements used in the calculation. The number of significant figures in the answer should match the least number of significant figures in the measurements.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
to .0251 grams or 2.51 x 10-2 grams
Three significant figures: two before the decimal point and one after.
It depends on the characteristics of the preparations being compared. If they are both standardized and follow a similar protocol, then the measurements should be comparable. However, if there are significant differences in the preparations or protocols used, the measurements may not be directly comparable.
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
measurements should be made precisely to ensure accuracy (:
You can only evaluate what you have measured (or you are just making things up). Monitoring is the process of obtaining measurements.
