Hey there!:
Molar mass FeF3 = 112.84 g/mol
Number of moles = mass of solute / molar mass
Number of moles = 24.0 / 112.84
Number of moles = 0.212 moles of FeF3
Hope that helps!
Answer:
435.38 L
Explanation:
From the question,
Applying ideal gas equation,
PV = nRT................... Equation 1
Where P = Pressure, V = Volume, n = number of moles, R = molar gas constant, T = Temperature.
Since Temperature and Pressure were constant,
V ∝ n
V/n = V'/n'.................... Equation 2
Where V and V' = the initial and final Volume of Ar respectively, n and n' = the initial and final moles of Ar respectively
make V' the subject of the equation
V' = Vn'/n............... Equation 3
Given: V = 100 L, n = 3.25 mol, n' = 14.15
Substitute into equation 3
V' = (100×14.14)/3.25
V' = 435.38 L
Answer:
A. 1 liter of water at temperature 75°C
Explanation:
According to kinetic molecular theory average kinetic energy of molecules are directly proportional to absolute temperature.
the quantity of the sample does't depend on kinetic energy only temperature
does so the choice with highest temperature is the correct choice
∵ 1 liter water at 75°C has highest average kinetic energy per molecule
