(c) has 3 significant figures, (a) has 2 sig figs, (b) has 2 sig figs, as 190 = 1.9 x 10^2, and (d) has 2 sig figs.

There are 4 sf. The trailing 0s in 4.00700 must be there for a reason and that reason is that they are significant. But, if you multiply a number with 6 sf by a number with 4 sf then the answer can have at most 4 sf.
What is the difference between 6500. and 6500? The first one would be considered to have a terminal decimal. This means that instead of simply writing the number as it is, a decimal is added to the end to represent significant figures (terminal decimals are most commonly used in scientific notation). Therefore, when 6500 would only be considered as to having 2 significant figures, 6500. has 4 significant figures.
When using division or multiplication, the number of significant figures should be no more than the factor with the least number of significant figures. In this case, you have 35.896/6.25 so the answer should have only 3 significant figures (based on 3 SF in 6.25). The answer would be 5.74 m/sec.
Most likely it is a logarithm.

The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
There are 4 sf. The trailing 0s in 4.00700 must be there for a reason and that reason is that they are significant. But, if you multiply a number with 6 sf by a number with 4 sf then the answer can have at most 4 sf.
4 of them because there are four number. But remember the first number 7 in this value is the most significant one.
When multiplying/dividing measurements the answers needs to have the same amound significant figures as the one with the LEAST amount
Significant figures are basically the amount of digits in a number. E.g. 2.576 has 4 significant figures 32.545 has 5 significant figures Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures. E.g. 0067.4 has 3 significant figures 67.400 has 3 significant figures 0067.400 has 3 significant figures. In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.
The most accurate answer is 0.2 mol/kg.Related Information:The number of significant figures in the final answer must be based on the given with the least number of significant figures which is 2L.
No, the one with the least.
The statement is false.
False
At least 1 and at most 7. It could be 3,999,999.9 rounded to 7 significant figures; It could be 3,999,999 rounded to 6 significant figures; It could be 4,000,015 rounded to 5 significant figures; It could be 4,000,429 rounded to 4 significant figures; It could be 3,999,999 rounded to 3 significant figures; It could be 4,049,999 rounded to 2 significant figures; It could be 4,492,467 rounded to 1 significant figure.
This is false. (I got this question on my test.)
