The pressure will not affect the rate of solution.

Answer: Option (c) is the correct answer.

Explanation:

Since, the substance added is a solid and particles of a solid are very closely held to each other because of strong intermolecular forces of attraction between them.

This makes them to have a definite shape and volume. Therefore, when pressure is applied on a solid then its particles will be least affected by it as they are already close to each other.

Whereas stirring, amount of surface area, and temperature will equally affect the rate of dissolution of the solid.

Hence, we can conclude that pressure is the factor that has least effect on the rate of solution of a solid in a liquid.

How many moles of an ideal gas are in a tank with a volume of 22.9 L at pressure of 14.297 atm at 12°C? ( Show work and units )
zzz [600]

Answer:

14 moles

Explanation:

For an Ideal gas,

PV = nRT...................... Equation 1

Where P = Pressure, V = Volume, n = number of mole, R = Molar gas constant.

make n the subject of the equation

n = PV/RT.................. Equation 2

Given: P = 14.297 atm, V = 22.9 L = 22.9 dm³, T = 12 °C = (12+273) K = 285 K.

Constant: R = 0.082 atm.dm³/K.mol

Substitute these values into equation 2

n = (14.297×22.9)/(285×0.082)

n = 327.4013/23.37

n = 14.009

n ≈ 14 moles
