Correct any entries in. the table that are

Solution: Here, we are going to identify the wrong entry of the significant figures in the given table.

Step1:

The following rules are followed to count the number of significant figures in a particular number:

1. All non-zero digits are significant.
2. Zeroes between two non zero digits are significant.
3. The zeroes preceding to the first non zero number(i.e., to the left of the first non zero number) are not significant.
4. All zeroes placed at the end or to the right of a number are significant provided they are on the right side of the decimal point.
5. In exponential notations, the numerical portion represents the number of significant figures.

Step2:

Based on the rules given above, we can say that two of the entries given in the table are wrong.

b)        0.00086 has two significant figures        [Rule 3]

c)        0.5672100 has seven significant figures        [Rule 4]
