Which measurement has five significant figures? 450.3 n 0.04503 n 45,300 n 4.5300 n

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)
