3. Ethanol has a density of 0.800 g/mL. <br> a. What is the mass of 225 mL of ethanol?
dedylja [7]

Since the ethanol has a density of 0.800 g/mL, the mass of the ethanol is 180 grams.

<u>Given the following data:</u>

  • Volume of ethanol = 225 mL
  • Density of lead ball = 0.800 g/mL.

To find the mass of the ethanol;

Density can be defined as mass all over the volume of an object.

Mathematically, the density of a substance is given by the formula;

Density = \frac{Mass}{Volume}

Making mass the subject of formula, we have;

Mass = Density \times Volume

Substituting the given parameters into the formula, we have;

<em>Mass of ethanol </em><em>=</em><em> 180 grams.</em>

chubhunter [2.5K]
Two Half Cell reactions are as,

Reduction:                   PbO₂  +  2e⁻   →     Pb²⁺  

As it is acidic medium reaction, so add H⁺ on reactant side as it has more number of oxygen atoms and add H₂O on product side, and balance tehe elements, So,
                             4 H⁺     +   PbO₂  +  2e⁻   →     Pb²⁺   +    2 H₂O      (1)

Oxidation:                        I⁻     →     I₂   +  1e⁻

Balance Number of elements along with electrons,

                                        2 I⁻     →     I₂   +  2e⁻                                    (2)

Compare eq. 1 and 2,

                             4 H⁺     +   PbO₂  +  2e⁻   →     Pb²⁺   +    2 H₂O

                                                           2 I⁻     →     I₂   +  2e⁻ 
                            ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻
                            PbO₂  +  2 I⁻  +  4 H⁺     →     Pb²⁺  +  I₂  +  2H₂O
