Answer:C.people with perfect understanding of science.
Answer : The volume of pure diamond is
Explanation : Given,
Density of pure carbon in diamond =
Moles of pure diamond = 23.7 moles
Molar mass of carbon = 12 g/mol
First we have to calculate the mass of carbon or pure diamond.
Molar mass of carbon = 12 g/mol
Now we have to calculate the volume of carbon or pure diamond.
Formula used:
Now putting all the given values in this formula, we get:
Volume =
As we know that:
So,
Volume =
Volume =
Therefore, the volume of pure diamond is
Answer:
0.22
Explanation:
Given, Mass of = 46.85 g
Molar mass of = 299.4 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given, Mass of = 125.5 g
Molar mass of = 46.07 g/mol
The formula for the calculation of moles is shown below:
Thus,
So, according to definition of mole fraction:
the process of changing one form of energy into another
Answer:
It would be 5.8 times 10^9cm
