To find the sum of 334.540 g and 198.9916 g, we add the two values together, resulting in 533.5316 g. When considering significant figures, the result should be rounded to the least number of decimal places in the original numbers, which is three decimal places (from 334.540 g). Therefore, the final answer is 533.532 g.
There is 1 significant figure in this measurement.
There are only one significant figure in 6000 g. Leading zeros are not considered significant figures.
The measurement of 417.32 g has five significant figures. Each non-zero digit and any zeros between them are considered significant in a decimal number.

There are 3 significant figures in 0.0000246 g.
2 Except that the fact that the figure is given as 3300 g instead of 3.3 kg suggests that the trailing 0s are significant.
2 significant figures.
2 significant figures.
Three - zeros between significant digits are significant.
143 g has three significant figures. The leading zeros are not considered significant.
The answer is 6*10^5 g.
The product of 0.12 g, 1.8 g, and 0.562 g should have the same number of significant figures as the measurement with the fewest significant figures, which is 0.12 g in this case. Therefore, the product should be expressed with two significant figures.
