3) How many atoms are in 14 moles of cadmium?
1 answer:
Answer:
atoms are in 14 moles of cadmium.
Explanation:
Cadmium is a white and silvery metal that is found in the curst of the earth.During the production process of metals such as lead, copper, zinc, cadmium is extracted
Cadmium is present in some foods and is emitted when fossil fuels like as coal and oil is used, smoking cigarettes. It is used in craft glazes, metal batteries, and coatings.
We know that 1 mole of Cadmium (Cd contains) 6.023*1023 atoms, which is Avogadro's number.
So in 14 Grams of Cadmium, the number of atoms present is,
=>14×number atoms present in one cadmium atom
=>

Explanation:
Formula to calculate specific rotation is as follows.
Specific rotation () =
where, = observed rotation
c = concentration in g/ml
l = path length in dm
It is given that,
c = = 0.02 g/ml
l = 20 cm = 2 dm (as 1 dm = 10 cm)
Therefore, calculate the specific rotation as follows.
Specific rotation () =
=
=
Thus, we can conclude that the specific rotation of this compound is .
