QuestionHow many significant figures are in 8000.0? a) 5 b) 3 c) 2 d) 4
Studdy Solution
STEP 1
Assumptions1. We need to find the number of significant figures in8000.0
STEP 2
The rules for determining the number of significant figures in a number are as follows1. All non-zero digits are considered significant.
2. Any zeros between significant digits are significant.
. Leading zeros are not significant.
4. Trailing zeros in a number containing a decimal point are significant.
STEP 3
Now, let's apply these rules to the number8000.0.
1. The number8 is a non-zero digit, so it is significant.
2. The zeros between the8 and the decimal point are not between significant digits, so they are not significant.
3. There are no leading zeros in this number.
. The zeros after the decimal point are trailing zeros in a number containing a decimal point, so they are significant.
STEP 4
Count the number of significant figures.
There is1 non-zero digit (8) and1 significant zero (the one after the decimal point), so the total number of significant figures is2.
So, the correct answer is c)2.
