marshall27 [118]

The question is incomplete, the complete question is;

In a laboratory experiment, students synthesized a new compound and found that when 12.23 grams of the compound were dissolved to make 228.1 mL of a benzene solution, the osmotic pressure generated was 4.55 atm at 298 K. The compound was also found to be non-volatile and a non-electrolyte. What is the molecular weight they determined for this compound?

Answer:

287.76 g/mol

Explanation:

From;

π = M R T

M = molarity

R= gas constant

T = temperature

number of moles = π * volume/RT

number of moles = 4.55 * 228.1/1000/0.082 * 298

number of moles = 1.037855/24.436

number of moles = 0.0425 moles

Molar mass = mass/number of moles

Molar mass = 12.23 grams/0.0425 moles

Molar mass = 287.76 g/mol

Which is a Characteristic of a non elecrolyte​
myrzilka [38]

Answer:

A nonelectrolyte is a substance that does not exist in an ionic form in aqueous solution. Nonelectrolytes tend to be poor electrical conductors and don't readily dissociate into ions when melted or dissolved. Solutions of nonelectrolytes do not conduct electricity.
