Question

14 - 18. a - e in order from most dense to least dense based on the facts provided. please list the substances a - e in order from most dense to least dense based on the facts provided. please write your answers in the spaces provided below. substance a: 8.2 g/cm³ substance b: 3.5 g³ and 30.0 g substance c: 10.0 g and 40 ml substance d: 0.5 g/cm³ substance e: 2.0 cm by 3.0 cm by 1.0 cm and 4.0 grams

Explanation:

Step1: Calculate density of Substance B

Density = $\frac{mass}{volume}$, for Substance B, density = $\frac{30.0g}{3.5cm^{3}}\approx8.57g/cm^{3}$

Step2: Calculate density of Substance C

Density = $\frac{10.0g}{40mL}$, since 1 mL = 1 $cm^{3}$, density = $\frac{10.0g}{40cm^{3}} = 0.25g/cm^{3}$

Step3: Calculate density of Substance E

Volume of Substance E = $2.0cm\times3.0cm\times1.0cm=6.0cm^{3}$, density = $\frac{4.0g}{6.0cm^{3}}\approx0.67g/cm^{3}$

Step4: Compare densities

We have density of Substance A = $8.2g/cm^{3}$, Substance B $\approx8.57g/cm^{3}$, Substance C = $0.25g/cm^{3}$, Substance D = $0.5g/cm^{3}$, Substance E $\approx0.67g/cm^{3}$

Answer:

B, A, E, D, C
