75.612.33 isn't even a number
which is the correct product of the significant figures 3.278 and 4.23.
75.6 times 12.33 = 932.148 correct to 6 significant figures
147.658 to two significant figures is 150.
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
33.0
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.
