The Lewis structure of Chloroacetate (H₂CClCO₂) is given below. In structure it is shown that carbon has a double bond with one oxygen atom and two single bonds with CH₂Cl and O⁻.
Formal Charge;
Formal charge is caculated as,
Formal charge = # of valence e⁻ - [# of lone pair of e⁻ + 1/2 # of bonded e⁻]
Formal charge on Oxygen (Highlighted Red);
Formal charge = 6 - [ 6 + 2/2]
Formal charge = 6 - [6 + 1]
Formal charge = 6 - [7]
Formal charge = -1

Answer:
Explanation:
Hello,
In this case, we can compute the mole fraction of benzene by using the following formula:
Whereas n accounts for the moles of each substance, thus, we compute them by using molar mass of benzene and cyclohexane:
Thus, we compute the mole fraction:
Next, for the molality, we define it as:
Whereas we also use the moles of benzene but rather than the moles of cyclohexane, its mass in kilograms (0.08074 kg), thus, we obtain:
Or just 0.990 m in molal units (mol/kg).
Best regards.
