Answer
Explanation:
Step1: Calculate density for 5.83g/2.2cm³
$\rho = \frac{5.83}{2.2} = 2.65$
Step2: Match 2.65 with density chart
Quartz has density 2.65
Step3: Calculate density for 378g/36.05cm³
$\rho = \frac{378}{36.05} \approx 10.49$
Step4: Match 10.49 with density chart
Silver has density 10.49
Step5: Calculate density for 25.5g/16cm³
$\rho = \frac{25.5}{16} \approx 1.59$
Step6: Match 1.59 with density chart
Sugar has density 1.59
Step7: Calculate density for 7.083g/0.9cm³
$\rho = \frac{7.083}{0.9} = 7.87$
Step8: Match 7.87 with density chart
Iron has density 7.87
Step9: Calculate density for 61.83g/3.2cm³
$\rho = \frac{61.83}{3.2} \approx 19.32$
Step10: Match 19.32 with density chart
Gold has density 19.32
