To determine the pOH assuming water is the universal solvent take the value of 10 ^ -14 and then divide it by the hydronium concentration and then take the negative logarithm of the final answer that is the solution to the hydroxide ion concentration in the solution.

Answer:
The answer to your question is letter A
Explanation:
Process
1.- Calculate the molecular mass of AlCl₃
Al = 1 x 27 = 27
Cl = 3 x 35.5 = 106.5
AlCl₃ = 27 + 106.5 = 133.5
2.- Find the number of ions of Cl using proportions
133.5 grams of AlCl₃ ------------- 3 ions of Chlorine
400.5 grams of AlCl₃ ------------ x
x = (400.5 x 3) / 133.5
x = 9
Given: C= 81.70% = 81.70g
H = 18.29% = 18.29g
<span>The number of moles is given by: n= Given mass (m)/Molar Mass (M)
</span>M of C = 12 g/mol
M of H = 1 g/mol
Thus, the number of moles of carbon = 81.70g / 12gmol= 6.83moles
and, the number of moles of hydrogen = 18.29/1g/mol = 18.29 moles
The ration of C moles with hydrogen :
H:C = 18.29moles/6.83moles= 2.67 ≈3
Thus, the empirical formula is C3H8
