Answer:
10 m
Explanation:
The mole fraction of FeCl₃ of 0.15, that is, per mole of solution, there are 0.15 moles of FeCl₃ and 1 - 0.15 = 0.85 moles of water.
The molar mass of water is 18.02 g/mol. The mass corresponding to 0.85 moles is:
0.85 mol × 18.02 g/mol = 15 g = 0.015 kg
The molality of FeCl₃ is:
m = moles of solute / kilogram of solvent
m = 0.15 mol / 0.015 kg
m = 10 m
O2 mol O2 2 mil CO2 O1molO2
Answer: The bookkeeper makes cash deposits and records journal entries related to cash, while the treasurer prepares the bank reconciliation.
Explanation: The bookkeeper in an organization is the person in charge of records keeping, his basic task is to keep financial records and therefore the bookkeeper has no business handling physical cash in an organization.
The financial secretary on the hand is in charge saving cash income and withdrawal of cash from an organization, this is done with the organization's accountant approval.
Answer: Option (1) is the correct answer.
Explanation:
When dissolved in water, ammonium phosphate 
completely dissociates into ions and it gets attached to the opposite ends of water.
Therefore, it is soluble in water.
Whereas silver sulfate 
slightly dissolves into water as it gives very less 
ions. Therefore, silver sulfate has low solubility.
On the other hand, both 
and 
are insoluble in water.
Thus, we can conclude that out of the given options, is most soluble in water.
