# sig fig

 what is a sig fig number of digits that are known plus 1 estimated digit how many sig figs do exact numbers have infinite how many sig figs do defined numbers have they're exact (100 cm=1m). are all non-zero numbers significant yes zeros to the left of nonzero numbers (are/are not) significant before or after a decimal? 0.0032 or 003200 not significant2 sig figs zeros between sig digits are/are not significant 502.001 are significant6 sig figs are zeros at the end of a number and to the right of a decimal significant? 5.00 yes.  there are 3 sig figs. Is a zero significant when it's to the right of a nonzero number and to the left of an implied decimal point 6200 no, there are only 2 sig figs how many sig figs do exact conversions have all numbers in exact conversions are significant (except 0's that are place holders). 0's to the right of a nonzero number and left of a decimal point are/are not significant? 55300.0 are significant. there are 5 sig figs what's the rule if the digit to be dropped is greater than 5? round up if the digit to be dropped is less than 5 round... round down if the digit to be dropped is exactly 5 without numbers to the right... the number to the left is used for rounding.  If odd, round upif even, it remains 5. where is the proper place for a decimal in scientific notion after the first nonzero digit what's the rule about calculating sig figs the result of the calculation cannot be more percise than the lease percise measurement in the calculation. how many sig figs 190.6 X 2.3=438.28 drop the last 3 digits to get 440, because you round up first.  Correctly written as 4.4 X10^2 when adding and subtracting it is important that the resulting number be rounded to have the same amount of decimal places as the value with the ____  decimal places. 125.17 129. 52.2 + --- 306. fewest decimal places.  Number rounded down after the decimal=306 or correctly written as 3.06X10^2 calculate (1.039-1.020)/1.039= 0.018 or 1.8X 10^-2 SI system basic measure of length meters SI measure of mass kilogram Si unit of measure of temp kalvin K SI unit of measure tim second s SI unit of measure of substance mole m SI unit measure of electric current ampere A SI unit measure of luminous intensity candela cd exe E is the numerical value for SI 10^18 Penta P is SI value for 10^15 tetra T is the SI value for 10^12 giga is the SI value for 10^9 mega is the SI value for 10^6 kilo is the SI value for 10^3 hecto h is the SI value for 10^2 da is the SI value for 10^1 deci d is the SI value for 10^-1 centi c is the SI value for 10^-2 milli m is the SI value for 10^-3 micro is the SI value for 10^-6 nano n is the SI value for  10^-9 pico p is the SI value for 10^-12 femto f is the SI value for 10^-15 atto a is the SI value for 10^-18 Authorstudysuccess ID173496 Card Setsig fig Descriptionch 2 slides, sig fig Updated2015-04-05T18:03:06Z Show Answers
