If you dissolve 23 g of ammonium chloride in 500.0 mL of water, what is the molar concentration of the solution?

Chemistry

Burka [1]4 years ago

Molar concentration is the amount of solute in moles divided by 1 liter of solvent. Then to answer this question, you need to convert the 23g of ammonium chloride into mole unit. Since the mass of nitrogen = 14, helium =1, and chlor= 35.453 then the molecular mass of (NH4)Cl should be: 14+4+35.453= 53.5

Then, the molarity should be: 23g/ (53.5gr/mole)/ (500ml/1000ml)= 0.86molality

. Explain why, in the sample calculations, 0.1 g of the unknown produced a GREATER freezing point depression than~e same mass of
dimulka [17.4K]

Answer

Naphthalene is a non electrolyte

If the unknown compound is an electrolyte it gives 2 or more ions in solution

( NaCl >> Na+ + Cl- => 2 ions

Ca(NO3)2 >> Ca2+ + 2 NO3- => 3 ions)

the f.p. lowering is directly proportional to the molal concentration of dissolved ions in the solution )

For naphthalene

delta T = 1.86 x m

for a salt that gives 2 ions

delta T = 1.86 x m x 2

hence the lowering in freezion point of unkown is greater then napthalene

Maya made this picture to represent a chemical reaction:
Minchanka [31]

Answer:

It is neither a synthesis reaction nor a decomposition reaction because two reactants form two products.

Explanation:

This reaction would be considered a single replacement reaction.
