Answer :

(a) There are 3 significant figures.

(b) There are 1 significant figures.

(d) There are 6 significant figures.

(e) There are 3 significant figures.

(f) There are 3 significant figures.

(g) There are 4 significant figures.

Explanation :

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures.All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures.All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures.All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures.All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures.All zeroes used solely for spacing the decimal point are not significant. For example : 8000 has one significant figure.The exponential digits present in scientific notation are not significant, only decimal digits the significant. For example: $1.9\times 10^{9}$ has 2 significant figures (1 and 9).
