Which of the following compounds will form an electrolyte in solution?
a. mgcl₂
b. c₆h₁₂o₆
c. c₂h₅oh
d. c₅h₁₂

what is the molarity of a 785 ml solution that contains 6.5 moles of hcl?
a. 8.3 m
b. 0.008 m
c. 121 m
d. 0.12 m

1) The correct answer is option A.

2) The correct answer is option A.

Explanation:

1) Electrolytes are the substance which break down into ions when dissolved in water and thus from current conducting liquid solutions .

These compounds in solid form does not conduct electricity due to the absence of free ions.

Magnesium chloride dissociate into its constituent ions when dissolved in water.

Magnesium chloride is the correct answer.

2) Molarity of a 785 ml solution that contains 6.5 moles of HCl.

Volume of solution = 785 mL = 0.785 L

Moles of HCl = 6.5 mol

Hence, the correct answer is option A.

your answer would be “dry”
