Using a mass of 1. 8 g and the volume displaced by the sample, calculate the sample's density. Question 17 options: 0. 17 g/mL 0
LUCKY_DIMON [66]

The sample's density with respect to the volume it displaces is equal to: C. 0. 60 g/mL

<u>Given the following data:</u>

  • Mass = 1.8 grams
  • Initial volume = 20 mL
  • Final volume = 23 mL

To calculate the sample's density:

First of all, we would determine the volume displaced by the sample;

Volume \;displaced = 23-20

Volume displaced = 3 mL

Density can be defined as mass all over the volume of an object. Thus, density is mass per unit volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = \frac{Mass}{Volume}

Substituting the given parameters into the formula, we have;

Density = \frac{1.8}{3}

Density = 0.60 g/mL
