1. Accuracy? ANS >>> Closeness of measurements to the TRUE VALUE of what
is being measured
2. Precision? ANS >>> Closeness of a SET of measurements
3. How do you calculate Percent Error? ANS >>> I experimental-accepted I
, x 100
accepted value
4. Are zeros infront of non-zero digis significant? ANS
>>> Nope! ex ANS >>> 0.0071 is only 2 sig figs
5. Are zeros at the end of a number and to the right of the decimal significant?-
ANS >>> Yep!
ex ANS >>> 9.100 is 4 sig figs
6. Addition/Subtraction in regards to sig figs? ANS >>> Round numbers to
the least number of decimal places
7. Multiplaction/Division in regards to sig figs? ANS >>> Round answers to
the least amount of sig figs
8. # of e- equal ANS >>> the # of p+
9. Atomic Mass? ANS >>> Number of protons in the nucleus (number on the left
bottom corner of the chemical symbol)
is being measured
