How many sig figs are in the number 2?
There is 1 sig fig in the number 2.
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.
What is 4251 in standard scientific notation?

346.7500 has five significant figures?
No, it actually has seven significant figures. Basic rule: (1)When number has decimal point---count from left to right counting all numbers after the first non-zero number ex.-->.009367 has 4 sig figs ex.-->9.367 has 4 sig figs ex.-->9.367000 has 7 sig figs (2)When number doesn't have a decimal point---count right to left counting all numbers after the first non-zero number ex.-->12 has 2 sig figs ex.-->120 has 2 sig figs ex.-->1207800 has 5 sig figs
How do you round to a significant figure?
When adding or subtracting, follow these steps to find a sig figs answer: 1) Add/Subtract numbers regularly. 2) Determine which measurement has the least decimal places. 3) Round final answer to the same number of decimal places. When multiplying or dividing, follow these: 1) Count the number of sig figs in the numbers you are multiplying/dividing. 2) Multiply/Divide regularly. 3) Round final answer to the same number of sig figs as the measurement with the fewest sig figs.
