3 significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
4, assuming the 0 at the end is to indicate the degree of precision.
There are 2 significant figures in this number.
3.774 is to 4 significant figures (count them)
The number 0.00038 has two significant figures. Significant figures are digits that carry meaning contributing to the precision of a number. In this case, the zeros before the 3 and 8 are not considered significant because they are leading zeros that simply indicate the decimal's placement. The 3 and 8 are the significant figures in this number.
There are only one significant figure in the number 20000. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, the zeros in 20000 are not considered significant because they are serving as placeholders to indicate the magnitude of the number rather than its precision.
The number 20.0 has three significant figures. The zeros at the end of the number after the decimal point are considered significant because they are placeholders to indicate the precision of the measurement. Therefore, all digits in 20.0 are significant.
142.617 has 6 significant figures and should not be confused with the number of decimal places to which the number is given which is 3dp. To 5 significant figures, the answer is 142.62 To 4 significant figures, the answer is 142.6 To 3 significant figures, the answer is 142 To 2 significant figures, the answer is 140 (the final zero is retained to indicate the position of the decimal point which , if shown, would be 140.0 To 1 significant figure, the answer is 100
Three significant figures are in this number.
3 significant figures.
If the conversion factor is exact, then the number of significant figures in the answer is the same as the number of significant figures in the original number.If the conversion factor is an approximation, then the number of significant figures in the result is the lesser of this number and the number of significant figures in the original number.
642000 expressed as four significant figures is 6.420e5
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are six significant figures in this number (i.e. all the figures here are significant).
There are 3 significant figures in this number.
