Determine the number of significant figures in the measurement quantity: 2600. kg.

2600 kg has 4 significant figures

Explanation:

Any different number to zero is a significant figure

For example, 1.8 → 2 significant figures

When you have 0 in the middle of two numbers, we consider it as a significant number

For example, 3.02 → 3 significant figures

When you have 0 on the left in the measure, we do not consider as a sgnificant figures

For example 0.0010 → 2 significant figures (10)

3.0 → 2 significant figures (0 is on the right, not the left)
