Question

2
3
4
5

Answer 1

The measurement 0.0450 liters has four significant figures. Here's the breakdown of the significant figures:

• The leading zeros (the two zeros before the 4) are not significant.
• The digits 4 and 5 are significant.
• The trailing zero after the 5 is significant because it comes after a decimal point.

Thus, the significant figures are 4, 5, and the trailing zero, making a total of four significant figures.
