1 mol = 6.022 x 10²³ atoms

In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.

So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃

But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃

1 mol=6.022 * 10²³ (atoms or molecules)
1.75 moles of (CHCl3) we have: 1.75 moles*(6.022 10²³ molecules)=1.05385  10²⁴ molecules.

a molecule of CHCl₃ have, 1 atom of C, 1 atom of H, and 3 atoms of Cl, therefore a molecule of CHCl3 have 1atom+1 atom +3 atom=5 atoms.
Therefore:

1 molecule (CHCl₃)--------------------------------5 atoms
1.058385 10²⁴ molecules (CHCl₃)-------------    x
x=(1.058385  10²⁴ molecules* 5 atoms) / 1 molecule≈5.26925  *10²⁴ atoms.

solution: ≈5.269  10²⁴ atoms.

is there a difference between a homogenouos mixture of hydrogen gas and oxygen gas, and a sample of vapor? explain?
marin [14]
Yes. In a homogeneous mixture the hydrogen and oxygen are not chemically combined; in water vapor, they are. You can separate a homogeneous mixture of hydrogen and oxygen by physical means, such as by cooling the mixture until the oxygen liquefies. If you cool water vapor you're just going to get liquid water and then ice - not two separate substances. That's because compounds can only be separated into their elements by chemical means.

kakasveta [241]

Answer:

Colloids (heterogeneous)

The difference between a colloid and a suspension is that the particles will not settle to the bottom over a period of time, they will stay suspended or float. An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water.
