High 5 Most Complicated Things About Sig Figs (Significant Figures)
Sig Figs, Sig Digs, Satan’s contribution to math and science — whatever you want to call them, they're one of the crucial hated and commonly confused ideas in science and math. Ignore them at your own peril, since these half factors off will add up and turn your A’s into B’s, or your B’s into C’s if you happen to’re not careful. The thing is, sig figs really are NOT THAT HARD to master, and should you know these 5 ideas, then you’ll have a leg up on everybody else who still can’t determine the ins and outs of sig figs.
1. How To Deal With Zeros
Sandwiched zeros are significant
300 has one sig fig, but 303 has three sig figs because the center zero becomes significant
If trailing zeros come after a decimal level, then they are significant
1.000 (four sig figs) is a more exact measurement than 1.zero (2 sig figs)
If trailing zeros come after a number without a decimal level, then they're NOT significant
5,000 has 1 sig fig, but 5,000. has four sig figs because of the decimal level
Leading zeros are NEVER significant
0.0003 has one sig fig, but 0.3003 has 4 sig figs because the 0’s are sandwiched
2. How To Multiply and Divide With Sig Figs
Plug in every number exactly as it appears within the problem
Look on the number of sig figs in every number
Spherical your reply so it comprises the least number of sig figs out of all the numbers being multiplied or divided
ex: 325.0 (four sig figs) / 2.0 (two sig figs) = 162.5, but the reply ought to only have sig figs, so you’d spherical it to 160 (two sig figs; 0 just isn't a sig fig) as your reply
3. What About Multiplying With Unit Conversions?
The numbers you employ for unit conversions do not count as sig figs
ex: if you wish to convert 38.5 grams into kilograms, your answer would have 3 sig figs still, even if you happen to use the conversion 1kg/1,000g
4. Adding and Subtracting With Sig Figs
Sig Figs DO NOT MATTER when adding and subtracting numbers
Instead, your reply should include the least number of decimal places
ex: 4.32 + 5.1 should have one decimal point, so you discover the exact answer (9.42) and spherical it to a solution with one decimal level (9.4)
5. How To Measure Volumes With Sig Figs
There will typically be a curve, or meniscus, in the top of a liquid — always measure the bottom of the meniscus
If you find yourself measuring the amount of something in a beaker or graduated cylinder, look at each tick mark, then go one decimal point additional when recording your calculation
