What expression will produce an answer with the fewest significant figures?
22.3-9.7
Which expression will produce an answer with the fewest significant figures A 23.51 56.2 B 22.3 - 9.7 C 12.2 - 4.7 D 3460 - 1790?
its C :))
What is the sum of 2.7g and 2.47g exspressed in the correct number of significant digits?
5.2g When you add or subtract using significant figures, you round the answer to the fewest number of decimal places as the measurement with the fewest decimal places.
Examples in multiplication and division of significant figures?
Multiplication and DivisionRound the answer to the same number of significant figures (sig figs) as the measurement with the fewest sig figs in the problem.34.9cm x 4.7cm = 164.03cm2 = 160cm2 (rounded to two sig figs)271.0g/99.8cm3 = 2.71543g/cm3 = 2.715 (rounded to four sig figs)Addition and SubtractionRound the answer to the fewest decimal places as the measurement with the fewest decimal places.9.45kg + 8.329kg = 17.78kg (rounded to two decimal places)
Which of the 3-D figures has the fewest edges?
a sphere has no edgesOf the solids with planar faces and line edges the tetrahedron has the fewest edges and faces. (Four faces and six edges)

What is the significant figures 4.884 x 2.25?
4.884 has four significant figures and 2.25 has three significant figures. 4.884 x 2.25 = 10.989 = 11.0 rounded to three significant figures. When multiplying or dividing, the result must have the same number of significant figures as the number in the problem with the fewest significant figures.
How many significant figures would be in the answer of 2.2458 m x 0.55 m?
Two. When multiplying or dividing the answer is rounded to the fewest significant figures in the given measurements. 0.55 has only two significant figures, so the answer can have only two significant figures.
What is the significant figures for 13.5 x 3.00?
When multiplying, the number of significant numbers in the answer should be the same as the fewest significant figures in the problem. Both 13.5 and 3.00 have three significant figures, so the answer will have three significant figures. 13.5 x 3.00 = 40.5 exactly (no need to round).
What is the sum of 2.7g and 2.47g exspressed in the correct number of significant digits?
5.2g When you add or subtract using significant figures, you round the answer to the fewest number of decimal places as the measurement with the fewest decimal places.
When multiplying and diving measured quantities the number of significant figures in the result should be equal to the number of significant figures in?
The final answer.is only as accurate as the least accurate component in the calculation, so use the significant figures of the measurement with the fewest.
Why when you make measurements should the answer only have the same number of significant figures as the measurement with the fewest significant figures?
This is because the uncertainty in your answer is determined by the least precise measurement. It's no use expecting your answer to be known to 4 decimal places if you are only measuring to the nearest whole mile.

What is the rule for significant figures when adding or subtracting decimals?
When adding and/or subtracting, your answer can only show as many decimal places as the measurement having the fewest number in the decimal places.
What is the number of moles and the number of atoms in 2.30 grams of sodium?
From the periodic table, 1 mole of sodium is 22.989770g. To find the number of moles in 2.30g, multiply the known mass x (1mol/22.989770g). 2.30g Na X (1mol Na/22.989770g Na) = 0.100mol Na* * The answer is in 3 significant figures because 2.30g has 3 significant figures. When you multiply or divide, the answer is rounded to the same number of significant figures as are found in the number with the fewest significant figures.
How many significant figures should be in the answer obtained by adding 0.04 31.2 and 100.0?
The answer is limited to the number with the fewest digits of precision (digits after the decimal point). (2 digits of precision)
