Question

Three samples, each of a different substance, are weighed and their volume is measured. The results are tabulated. List the substances in order of decreasing density. Mass volume substance i 12.0 g 10.0 ml substance ii 10.0 kg 10.0 l substance iii 10.0 mg 12.0 μl

Answer 1

Answer;

Substance i > Substance ii > Substance iii

Step-by-step explanation:

Substance i :

Data Given;

Density = ?

Mass = 12 g

Volume = 10 mL

Formula Used;

Density = Mass ÷ Volume

Putting Values,

Density = 12 g ÷ 10 mL

Density = 1.2 g.mL⁻¹

Substance ii :

Data Given;

Density = ?

Mass = 10 Kg = 10000 g

Volume = 10 L = 10000 mL

Formula Used;

Density = Mass ÷ Volume

Putting Values,

Density = 10000 g ÷ 10000 mL

Density = 1 g.mL⁻¹

Substance iii :

Data Given;

Density = ?

Mass = 10 mg = 0.01 g

Volume = 12.0 μl = 0.012 mL

Formula Used;

Density = Mass ÷ Volume

Putting Values,

Density = 0.01 g ÷ 0.012 mL

Density = 0.833 g.mL⁻¹
