Question

The mass of an object is 13.76 g. the volume of the object is 2.83 ml. what is the density of the object to the correct number of significant figures?

Answer 1

Answer:

D ≈ 4.86 g/mL

Explanation:

Density = Mass over Volume

D = m/V

Step 1: Define variables

m = 13.76 g

V = 2.83 mL

D = unknown

Step 2: Substitute and Evaluate for Density

D = 13.76 g/2.83 mL

D = 4.8621908127208480565371024734982 g/mL

Step 3: Simplify

We are given 3 sig figs.

4.8621908127208480565371024734982 g/mL ≈ 4.86 g/mL
