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
