1) As many as you need for a particular purpose.
2) In any case, since this number is probably the result of some calculation, the answer should not look more accurate than what is justified by the original data. For example, if you multiply two numbers, one with 4, one with 5 significant digits, the answer should not have more than 4 significant digits.

How many significant figures should be retained when performing addition and subtraction operations involving measurements with different numbers of significant figures?
When performing addition and subtraction operations with measurements of different significant figures, the result should be rounded to the same number of decimal places as the measurement with the fewest significant figures.
What determines the number of significant figures in density calculations?
The accuracy of the measurement device determines the number of significant figures that should be retained in recording measurements.
When multiplying and dividing measured quantities the number of significant figures in the result should be equal to the number of significant figures in what?
The number of significant figures should be equal to the significant figures in the least precise measurement.
How many significant figures do 14500?
The number 14500 has five significant figures. Significant figures are the digits in a number that carry meaning contributing to its precision. In this case, all the digits in 14500 are considered significant because they are all non-zero and are part of the measurement.
What concludes the number of significant figures that should be maintain in recording the measurement?
The number of significant figures in a measurement is determined by the precision of the measuring instrument. Include all certain digits plus one uncertain digit (estimated or interpolated). Nonzero digits, zeros between nonzero digits, and trailing zeros in numbers containing a decimal point are considered significant.
How many significant figures should be in the resulting calculations?
The least number of significant figures in any number of the problem determines the number of significant figures in the answer.
How do significant figures work when multiplying numbers?
When multiplying numbers, the result should have the same number of significant figures as the number with the fewest significant figures.
How many significant figures should be reported in the answer to 14.1 9?

The number 5321 has 4 significant figures.
If you multiplied 6774m by 46m how many significant figures should you report in your answer?
You should report your answer to three significant figures because 6774m has four significant figures and 46m has two significant figures, so the least number of significant figures between the two numbers determines the number of significant figures in the product.
How do you multiply numbers while considering significant figures?
