Answer:
C ≈ 1.44 × 10⁻³ mol/m³
Explanation:
The given information are;
The liquid volume the pond can hold = 104 m³
The volume of inflow into the pond = 5 m³/h
The volume of outflow into the pond = 5 m³/h
The concentration of the chemical in the inflow water = 0.01 mol/m³
The concentration of the chemical discharged directly into the water = 0.1 mol/h
The concentration, , of chemical that enters the water through inflow per hour is given as follows;
= 0.01 mol/m³ × 5 m³/h = 0.05 mol/h
The concentration, , of chemical that enters the water through direct discharge per hour is given as follows;
= 0.1 mol/h
The total concentration that enters the pond per hour is given as follows;
+
= 0.1 mol/h + 0.05 mol/h = 0.15 mol/h
Whereby the water in the pond properly mixes with the pond, we have;
The concentration of chemicals (C) in the outflow water = 0.15 mol/(104 m³) ≈ 0.00144 mol/m³
C ≈ 1.44 × 10⁻³ mol/m³.

In the problem, we are tasked to solved for the amount of carbon (C) in the acetone having a molecular formula of C 3 H 6 O. We need to find first the molecular weight if Carbon (C), Hydrogen (H), Oxygen (O).
Molecular Weight:
C=12 g/mol
H=1 g/mol
O=16 g/mol
To calculate for the percent by mass of acetone, we assume 1 mol of acetone.
%C=
%C=62.07%
Therefore, the percent by mass of carbon in acetone is 62.07%
