How many molecules are in 1.75 mol of CHCl3

Chemistry
2 answers:
Sloan [31]2 years ago
4 0

Answer:

1.0535×10(exponent24)

Explanation:

N (number of molecules)

n(number of moles)

L( Avogadro's constant )

N=n×L

N=1.75×6.02×10(exponent 23)

Explanation:

In one mole we always have:

1 mol = 6.02 X 10²³ molecules

So emulates simple rule of 3 we will have;

1 mol ----------> 6.02 X 10²³

1.75 moles ----> X

X = 1.0535 X 10²⁴ molecules

Hope this helps, Good studies!

These could all go either way, hardness and other special properties are what I'm guessing would be the most accurate in determining the kind of material.
luster, cleavage, streak, and color can all be affected by other factors. but I guess cleavage would also be accurate. so I guess hardness special properties and cleavage would be the most reliable.

Lab report for physical and chemical changes??!
slega [8]

Answer:

[See Below]

Explanation:

✦ Physical Changes:

  ✧ Is when the form changes, but not the chemicals in that form.

  ✧ An example of this would be chopping wood. It's still wood but it's a different size now. It's easier to burn it since it's smaller.

✦ Chemical Changes:

  ✧ Is when the chemicals inside that form change to something else entirely

  ✧ An example would be an egg, when you cook the egg it can turn into being scrambled or fried. But you can't eat the raw egg until the chemicals change.

What is the average mass of a single silicon atom in grams?
torisob [31]

1 mol of Silicon = 28.0855 g (in average)

then

1 mol = 6.022*10^23 atoms

then

28.0855/(6.022*10^23) g/atom

4.66381*10^-23 g per atom

Calculate the entropy change for the surroundings of the reaction below at 350K: N2(g) + 3H2(g) -&gt; 2NH3(g) Entropy data: NH3
krek1111 [17]

Answer : The entropy change for the surroundings of the reaction is, -198.3 J/K

Explanation :

We have to calculate the entropy change of reaction (\Delta S^o).

\Delta S^o=S_{product}-S_{reactant}

\Delta S^o=[n_{NH_3}\times \Delta S^0_{(NH_3)}]-[n_{N_2}\times \Delta S^0_{(N_2)}+n_{H_2}\times \Delta S^0_{(H_2)}]

where,

\Delta S^o = entropy of reaction = ?

n = number of moles

\Delta S^0{(NH_3)} = standard entropy of NH_3

\Delta S^0{(H_2)} = standard entropy of H_2

\Delta S^0{(N_2)} = standard entropy of N_2

Now put all the given values in this expression, we get:

\Delta S^o=[2mole\times (192.5J/K.mole)]-[1mole\times (191.5J/K.mole)+3mole\times (130.6J/K.mole)]

\Delta S^o=-198.3J/K

Therefore, the entropy change for the surroundings of the reaction is, -198.3 J/K
