If an object has mass `0.2876 g`, then find the mass of nine such objects.
Strategy: Follow rule 3, but keep in mind that extact numbers obtained from determinos (e.g. dozen) or by counting the number of objects have an infinite number of significant figures.

Explanation

To find the mass of nine objects, each with a mass of 0.2876 g, we can follow these steps:

### Step 1: Identify the mass of one object
The mass of one object is given as:
\[ \text{Mass of one object} = 0.2876 \, \text{g} \]
