Answer:
a) 0.000896 = 3 significant figures
b) 30089 = 5 significant figures
c) 300 = 1 significant figure
d) 900.00 = 5 significant figures
e) 345.89 = 5 significant figures
Step-by-step explanation:
To determine the number of significant figures in a given measurement, you need to identify the non-zero digits and any zeros that are considered significant. Here's how you can do it for each of the provided measurements:
a) 0.000896: There are 3 significant figures in this measurement. The digits 8, 9, and 6 are considered significant. Leading zeros are not considered significant.
b) 30089: There are 5 significant figures in this measurement. All the digits 3, 0, 0, 8, and 9 are significant.
c) 300: The number 300 has 1 significant figure. Trailing zeros are not considered significant unless they are after a decimal point. If the measurement was 300.0, then it would have 4 significant figures.
d) 900.00: There are 5 significant figures in this measurement. All the digits 9, 0, 0, and the trailing zeros after the decimal point are significant.
e) 345.89: There are 5 significant figures in this measurement. All the digits 3, 4, 5, 8, and 9 are significant.
In summary:
a) 0.000896 = 3 significant figures
b) 30089 = 5 significant figures
c) 300 = 1 significant figure
d) 900.00 = 5 significant figures
e) 345.89 = 5 significant figures
