The correct representation when the number 0.007225 is rounded off to three significant figures is 0.00722
4,566 to 3 significant figures is 4,570.
0.081778 to two significant figures is 0.082
It is: 62 kg
What is 2.009 rounded to 2 significant figures
There are four significant figures in 0.1111.
which is the correct product of the significant figures 3.278 and 4.23.
4,566 to 3 significant figures is 4,570.
75.6 times 12.33 = 932.148 correct to 6 significant figures
0.081778 to two significant figures is 0.082
147.658 to two significant figures is 150.
776,890 in four significant figures is 776,900.
6,762 to 3 significant figures is: 6,760
That is correct.
Significant figures are very important when it comes to calculations. If the mass of an electron is 9.10939 x 10-31 then its significant figures are: 9 x 10^-31( correct 1 significant figure), 9.1 x 10^-31 kg ( correct to 2 significant figures), 9.11 x 10^-31 (correct to 3 significant figures), and 9.109 x 10^-31 (correct to 4 significant figures).
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
Nothing
3 of them.
