Which measurement has five significant figures?

450.3 n
0.04503 n
45,300 n
4.5300 n

Explanation:45,300N

4.5300 N

Explanation: I just took the test.

28.705 cm

Explanation:

Hello,

In this case, for rounding the number to five significant figures we must "cut" it at 5 so we hide the 3, therefore it turns out:

28.705 cm.

Moreover, we must realize that since such 3 is less than five, we do not modify the previous five to six, case which would happen if that three has changed to five or more.

Regards.

45,300 N

Explanation:

The significant figures are the digits that cannot be eliminated from the number without changing its value. Let's analyze each case:

450.3 N --> this number has 4 significant figures: 4, 5, 0, 3

0.04503 N --> this number has 6 significant figures: 0, 0, 4, 5, 0, 3

45,300 N --> this number has 5 significant figures: 4, 5, 3, 0, 0

4.5300 N --> this number has 3 significant figures: 4, 5, 3 (the two final zeroes can be removed from the number without changing its value)
