The number of grams : 17.082 g
<h3>Further explanation</h3>
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
453.9 mL of 0.237 M calcium acetate
MW Ca(C₂H₃OO)₂ : 158,17 g/mol
Answer:
In fluorine, the electrons are tightly held to the nuclei. The electrons have little chance to wander to one side of the molecule, so the London dispersion forces are relatively weak. At a low enough temperature the molecules will all be solids. At a high enough temperature they will all be gases.
Umm. False i guess I don’t really know
<u>Answer 45 :</u> This statement is true.
Explanation :
We are taking an example of carbon (C) with atomic number 6 and atomic mass 12.
As we know that the number of protons and number of electrons are equal to the atomic number.
The atomic number of carbon is 6. So, the number of protons and the number of electrons is equal to 6.
And, the number of neutrons = Atomic mass - Atomic number = 12 - 6 = 6
Hence, this statement is true.
<u>Answer 46 :</u> This statement is true.
Explanation :
We are taking an example of oxygen (O) with atomic number 8.
The electronic configuration of oxygen (O) will be,
Now we have to calculate the number of electrons from the electronic configuration.
The number of electrons = 2 + 2 + 4 = 8
Hence, this statement is true.
