Explanation:
The given data is as follows.
Volume = 1 L, Concentration of Ca = 5 ppm or 5 mg/L
As 1 mg = 0.001 g so, 5 mg /L will be equal to 0.005 g/l. Molar mass of calcium is 40.078 g/mol.
Hence, calculate molarity of calcium as follows.
Molarity of Ca =
=
Molarity of Ca =
Hence, molarity of is
. Since, volume is same so, moles of calcium chloride will be
.
Thus, we can conclude that mass of will be as follows.
(molar mass of
= 110.984 g/mol)
= 0.0138 g
Thus, we can conclude that mass of is 0.0138 g.
Answer:
⇒D_AB= 1.21×10^(-9)
Explanation:
Wike chang equation is given as:
Where
D_AB= diffusivity of chlorine in water
Φ= 2.26 for water as solvent
ν= 0.0484 for chlorine as solute
M_B = Molecular weight of water
τ= temperature=289 K
μ= viscosity = 1.1×10^{-3}
Now putting these values in the above equation we get
⇒D_AB= 1.21×10^(-9)
