Answer:
the density of lithium will be equal to: 0.582 g/cm^3
Explanation:
We have the following data:
a = 430 pm = 4.3x10^-8 cm
molar mass of lithium MM = 6.97 g/mol
Since the cubic cell of lithium is cubic centered in the face, its value of Z will be equal to 4
Avogadro´s number AN = 6.022x10^23 particles/mol
using the following formula we will calculate the density of lithium:
d = (Z*MM)/(a^3*AN) = (4*6.97)/((4.3x10^-8)^3*(6.022x10^23)) = 0.582 g/cm^3
Following reaction shows the preparation of
Nitrile from
Amide. In this reaction
Thionyl Chloride (SOCl₂)is reacted with Amide, which produced nitrile along with
SO₂ and
HCl gas. The
importance of this reaction is the removal of byproducts (i.e SO₂ and HCl). As both SO₂ and HCl are
gases so no extra workup is required to remove them. The
mechanism of reaction is as follow,
