<h3>Answer;</h3>

                                 Substance i > Substance ii > Substance iii

<h3>Explanation:</h3><h3><em><u>Substance i</u></em><em> :</em></h3>

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

<h3><em><u>Substance ii</u></em><em> :</em></h3>

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

<h3><em><u>Substance iii</u></em><em> :</em></h3>

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
