There is one significant digit in 0.05 (the 5... the zero before it is a placeholder) and two significant digits in 3.1. So your answer should have one sig fig: 0.05 x 3.1 = 0.155 = 0.2 (with correct # of sig figs)

The product of 0.05 and 3.1 is 0.16 (rounded to two significant figures). When multiplying numbers with different levels of precision, the result should be rounded to the same number of significant figures as the least precise number, which in this case is 0.05.

What would 120.7 be using significant figures?
The number 120.7 contains 4 significant figures. You start counting once you see any non-zero number. Any number after a decimal place is counted. The zero counts because it is a "captive" zero, which are always counted.
How many significant figures are there in 3400?
The number 3400 has two significant figures. The rules for significant figures can be found by using the link to our friends at Wikipedia.
The significant figures in a measurement include?
The significant figures in a measurement include all known digits plus one estimated digit. All non-zero digits are considered significant, zeros between non-zero digits are significant, and zeros at the end of a number and after a decimal point are significant.
How would you record a measurement of 16490 grams using only 2 significant figures?
The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1". When 16490 is rounded off to 2 significant figures then the first figure to be discarded is 4. As this is less than 5 then the previous figure (6) is not increased by 1. 16490 to 2 significant figures is 16000.

Using proper signification figures what is the answer to the problem 55.0 m s 3.027 s?
It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.
How many significant figures are in the measurement of 1.050 L?
Significant figures are calculated using various rules.ÊAll non-zero numbers are significant and all zeros that are to the right of the decimal point as well as at the end of a number are significant.ÊTherefore, 1.050L has 4 significant figures.

How many significant figures are in 74.30?
Answer: four. All written decimals are significant (even if it is 0).However if you have a physics computation where one number turns out to be x = 2.0 (2 significant figures) and the other turns out to be y = 37.15 (4 significant figures), then to compute the product x*y you should take the least of these significant numbers you are using. Hence, you will find thatx*y = 2.0 * 37.15 (= 74.30) = 74 (rounded to the nearest number with 2 significant digits only.)So, it depends on the context you are using this number in.
What is 86.346 plus 54.43 minus 9.5 using the correct number of significant figures?
86.346 +54.43 9.5 _______ 150.276 Now after we round the number and write it in significant figures , so it should look like this; 150 why? because when we need to round a number using the significant figures , we must look for the smallest significant figures which is 9.5 .
