QuestionCount the significant figures in 0.0157 kg. [Choose]
Studdy Solution
STEP 1
Assumptions1. We are asked to find the number of significant figures in the measurement0.0157 kg. . We understand that significant figures are digits in a number that carry meaningful information about its precision.
STEP 2
To determine the number of significant figures in a measurement, we need to follow these rules1. All non-zero digits are considered significant.
2. Any zeros between significant digits are significant.
. Leading zeros are not significant. They are only placeholders.
4. Trailing zeros in a number containing a decimal point are significant.
STEP 3
Now, apply these rules to the given measurement0.0157 kg.
STEP 4
First, identify the non-zero digits. These are all significant.
Here, the non-zero digits are1,, and7.
STEP 5
Next, identify any zeros between significant digits. These are also significant.
In the measurement0.0157 kg, there are no zeros between significant digits.
STEP 6
Then, identify any leading zeros. These are not significant.
In the measurement0.015 kg, the leading zeros are the zeros before the1. These are not significant.
STEP 7
Finally, identify any trailing zeros in a number containing a decimal point. These are significant.
In the measurement0.0157 kg, there are no trailing zeros after the decimal point.
STEP 8
Count the number of significant figures.
In the measurement0.0157 kg, there are3 significant figures (1,5, and7).
So, the measurement0.0157 kg has3 significant figures.
