Answer :

(1) The given number in 4 significant figures will be, $8.600\times 10^{-2}g$

(2) The given number in 4 significant figures will be, $4.310\times 10^{-1}g$

(3) The given number in 4 significant figures will be, $1.003\times 10^3g$

(4) The given number in 4 significant figures will be, $3.870\times 10^3g$

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.

(1) The given number 0.086 g converted into 4 significant figures.

In 0.086 g, there are 2 significant figures. Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, $8.600\times 10^{-2}g$

(2) The given number 0.431 g converted into 4 significant figures.

In 0.431 g, there are 3 significant figures. Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, $4.310\times 10^{-1}g$

(3) The given number 1003 g converted into 4 significant figures.

Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, $1.003\times 10^3g$

(4) The given number 3870 g converted into 4 significant figures.

Now we have to convert it into 4 significant figures.

The given number in 4 significant figures will be, $3.870\times 10^3g$

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
