Look at the numbers you are multiplying and dividing. Your answer should have the amount of sig figs that the smallest number has. Rules are as followed:
.00236 Has three sig figs. The zeros are used for "spacing". (.00200 also has three sig figs.)
.236 Has three sig figs.
100 Has one sig fig.
100. Has three sig figs due to the decimal point.
1.00 Has three sig figs.
The rules are confusing, but with practice, you should be able to understand them without a problem. I'm sure I have also forgotten to add one or two.
What else can I help you with?
How do you use sig figs with addition versus multiplication?
When your doing an addition/subtraction problem in chemistry the significant figures has to do with LEAST accurate decimal place. How do you know which one is the least ACCURATE? Think of it this way: the more numbers you have following a decimal, the MORE accurate it is. And likewise, the fewer numbers following the decimal, the least it is accurate. Look at 2.00 + 3.1 + 4.175 See how the least accurate decimal place is tenths in 3.1? Therefore your final anwer ends in 9.3. With multiplication and division, you count the total sig figs in each value and then round the final answer to that number of sig figs. Example: 8.965x18.2= 163.163 (without sig figs) The number with the least amount of sig figs is 18.2 (3 sig figs). So you would round 163.163 to simply 163. Does that make sense?
What is the rule of Estimating the decimals to significant figure?
In addition and subtraction you take the most number of sig figs. 312.45 - 3.0 = 3.0945 X 10^2 5 sig figs 2 sig figs answer needs to have 5 sig figs In multiplication and division it is the least number. 312.45 X 3.0 = 9.4 X 10^2 5 sig figs 2 sig figs answer needs to have at MOST 2 sig figs in decimals if there is no number before the decimal, i.e.; 0.xxxx then leading zeros do NOT count as significant. Meaning 0.000010 is only 2 significant figures. The 1 and the zero after the 1.
How will you determine the number of significant figure?
Determining Number of Significant Figures (Sig Figs)1.All non-zero numbers are significant. 6924 has four sig figs.2.Leading zeros are not significant. 0.0003679 has four sig figs.3.Zeros between other significant figures are significant. 0.00041092 has five sig figs.4.Trailing zeros are significant if there is a decimal. 0.046802000 has eight sig figs.

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)

0.0454
How many significaNT FIgures are used to express your final result of molecular weight?
to determine sig figs you eed to know how many sig figs are in the calclation. in adding and subtracting you answers are to the sig fig with the lowest dec point place. and in multiplication and dividing sig figs of answers determined by the number with the least sig figs in the calculation ex. 5.2 ( 2 sf) + 5.324 (4 sf) = 10.5 ( because 5.2 has the largest decimal place) 5.2 X 5.324 = 28 ( because 5.3 only has 2 sf so the answer ca only have 2sf)
Can you feed your guinea pig figs?
There is no nutritional problem with feeding your guinea pig figs, but it must be in very small amounts. Never give a guinea pig a whole fig at a time, for example.

How many significant figures should be retained in the result of the following calculation 12.00000 x 0.9893 plus 13.00335 x 0.0107?
there are 4 in the solution because the numbers are multiplied in the end, the solutions will have the same number of sig. figs. as the number in the problem with the lowest number of sig. figs. Ex: the lowest number of sig figs is 4 because 0.0107 has 4 sig figs.
