What is the mass % of ammonium chloride in a 1.73 m ammonium chloride aqueous solution at 20 °c?

The question is incomplete, here is the complete question:

What is the mass % of ammonium chloride in a 1.73 M ammonium chloride aqueous solution at 20 °C? The density of the solution is 1.0257 g/mL

The mass percent of ammonium chloride in solution is 9.03 %

Explanation:

We are given:

Molarity of ammonium chloride solution = 1.73 M

This means that 1.73 moles of ammonium chloride is present in 1 L or 1000 mL of solution.

Density of solution = 1.0257 g/mL

Volume of solution = 1000 mL

Putting values in above equation, we get:

Moles of ammonium chloride = 1.73 moles

Molar mass of ammonium chloride = 53.5 g/mol

Putting values in above equation, we get:

Mass of solution = 1025.7 g

Mass of ammonium chloride = 92.6 g

Putting values in above equation, we get:

Hence, the mass percent of ammonium chloride in solution is 9.03 %

answer: i would say b.

explanation:

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
