Answer: The density of the quartz is 2.68 g/mL
Explanation:
We are given:
Volume of graduated cylinder = 50.3 mL
Volume of quartz + graduated cylinder = 64.8 mL
Volume of quartz = [64.8 - 50.3] mL = 14.5 mL
To calculate the density of substance, we use the equation:
[tex]\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}[/tex]
Mass of quartz = 38.9 g
Volume of quartz = 14.5 mL
Putting values in above equation, we get:
[tex]\text{Density of quartz}=\frac{38.9g}{14.5mL}\\\\\text{Density of quartz}=2.68g/mL[/tex]
Hence, the density of the quartz is 2.68 g/mL
