6.023 ×
individual carbon atoms are there in one mole of carbon.
Mass of a 1 
atom= 12 amu
1 amu = 1.66 ×
gm
∴ 12 amu =1.99 ×
gm
∴Mass of a 1 atom=1.99 × gm
Mass of C in 1 mole = 12 gm
∴Total number of atoms of carbons in 1 mole = 12 ÷ 1.99 ×
∴Total number of atoms of carbons in 1 mole= 6.023 × atoms
6.023 × individual carbon atoms are there in one mole of carbon.
The number 6.023 × is known as Avogadro's number, which represents the number of individual atoms present in a one mole of substance with respect to atoms.

Answer:
The correct answer is 0.206 moles
Explanation:
According to the given scenario, the calculation of the number of moles of ammonium chloride is available in the resulting solution is given below:
Given that
Amount of 
is 11.0 grams
And, the volume is 235 mL
Now the molar mass of is 53.49g/mol
So, the number of moles presented is
= 11.0 ÷ 53.49
= 0.206 moles
hence, the number of moles of ammonium chloride are available in the resulting solution is 0.206 moles
A substance in a solid phase is relatively rigid, has a definite volume and shape.
<span>The atoms or molecules that comprise a solid are packed close together and are not compressible.<span>Because all solids have some thermal energy, its atoms do vibrate. However, this movement is very small and very rapid, and cannot be observed under ordinary conditions.</span></span>
Answer:
Mass of solvent is 1127.3 g
Explanation:
NaOCl → 3.62%
This percent means, that in 100 g of bleach solution, there are 3.62 g of NaOCl. So let's make a rule of three:
100 g of bleach solution have 3.62 g
1169.6 g of bleach solution may have (1169.6 . 3.62) /100 = 42.3 g
42.3 g is the mass of NaOCl in the solution
Mass of solution = Mass of solvent + Mass of solute
1169.6 g = Mass of solvent + 42.3 g
1169.6 g - 42.3 g = Mass of solvent → 1127.3 g
