How many atoms are in 1.75 mol CHCL3

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.

vesna_86 [32]
So, we have:
- molecular weight
- shape
- temperature
- kinetic energy
- mass
- density

Let's rule out the different options.
- molecular weight: Say you have a molecule of H2O. H2O can be a solid, liquid, or gas, but its molecular weight never changes throughout (It's still the same molecule, no matter what phase it is in). We can rule this out.

- shape: Let's pretend we have three identical closed containers, and we fill each one halfway with water, blocks of ice cubes, and water vapor. In the container with water, you will see that the water takes the shape of the container, but doesn't fill the entire container up. The ice cubes will stay ice cubes, assuming they don't melt, so they don't take the shape of the container. The vapor will fill up the entire container. Since all three are different, I would say yes, this could be a distinguishable feature.

- temperature: In general, I would say no, because every element/molecule has different boiling points and different vaporization points. So if you have a liquid at 5°C, you could also have a different element in solid form at 5°C. But if you're comparing a single type of molecule, it would have a boiling point and a vaporization point, so you <em>would</em> be able to tell between them.

- kinetic energy: Kinetic energy refers to how much movement there is in respect to each molecule. In solids, the molecules are packed tightly together and can't move very much, so they have lower kinetic energy. In liquids, they are less packed, but still restricted. And in gases, they can fly freely, so they will have much more kinetic energy than liquids or solids. This one's a yes.

- mass: No matter what form, there are still the same amount of molecules, and each molecule has the same mass as before. It won't change.

- density: Since the molecules are more spread out in gases, it will be less dense. Liquids will be more dense, and solids will have the greatest density. So, yes.

Conclusion: shape, kinetic energy, density, (and temperature if it's talking about a single type of molecule)

Answer with explanation and you’ll get brain list
Gwar [14]

Answer:

Option D.

Explanation:

  • 6H₂ + P₄ → 4PH₃

First we convert the given reactant masses into moles, using their respective molar masses:

  • 4.00 g H₂ ÷ 2 g/mol = 2 mol H₂
  • 6.20 g P₄ ÷ 124 g/mol = 0.05 mol P₄

0.05 moles of P₄ would react completely with (6*0.05) 0.3 moles of H₂. There are more H₂ moles than required, meaning H₂ is in excess and P₄ is the limiting reactant.

Now we<u> calculate how many PH₃ moles could be formed</u>, using the <em>number of moles of the limiting reactant</em>:

  • 0.05 mol P₄ * \frac{4molPH_3}{1molP_4} = 0.2 mol PH₃

Finally we <u>convert 0.2 mol PH₃ into grams</u>, using its <em>molar mass</em>:

  • 0.2 mol PH₃ * 34 g/mol = 6.8 g

So the correct answer is option D.
