Answer

Explanation:

Step1: Calculate density for Q4 samples

Sample1: $\frac{8}{2}=4$ g/mL; Sample2: $\frac{5}{5}=1$ g/mL; Sample3: $\frac{4}{2}=2$ g/mL; Sample4: $\frac{15}{3}=5$ g/mL

Step2: Identify sample with 2 g/mL

Sample3 has density 2 g/mL

Step3: Calculate density for Q5 samples

Sample1: $\frac{25}{15}\approx1.67$ g/mL; Sample2: $\frac{21.25}{5}=4.25$ g/mL; Sample3: $\frac{75}{7}\approx10.71$ g/mL; Sample4: $\frac{102}{24}=4.25$ g/mL

Step4: Identify two samples with 4.25 g/mL

Samples2 and 4 have density 4.25 g/mL

Answer:

Sample 3 Sample 2 and Sample 4
