The structural formula on the other hand is a representation of the molecular structure that shows all the atoms that form the molecule, arranged in a three dimentional space,

In this case we have the hydrogen ion, which is the simpliest case we can have.

Hydrogen ion is the hydrogen atom possitively charged as it has lost his electron. Therefore the structural formula is simply the following:

The Lewis formula is also very simple as this ion has no electrons and has no bonding to other atoms:

A solution of methanol and water has a mole fraction of water of 0.312 and a total vapor pressure of 211 torr at 39.9∘C. The vap

DaniilM [7]

Answer : This is not an ideal mixture.

Explanation :

Using Raoult's law :

$P_{Mixture}=p_{CH_3OH}+p_{H_2O}\\\\P_{Mixture}=x_{CH_3OH}\times p^o_{CH_3OH}+x_{H_2O}\times p^o_{H_2O}$

where,

$P_{Mixture}$ = total vapor pressure of mixture

$p^o_{CH_3OH}$ = vapor pressure of pure methanol = 256 torr

$p^o_{H_2O}$ = vapor pressure of pure water = 55.3 torr

$x_{H_2O}$ = mole fraction of water = 0.312

$x_{CH_3OH}$ = mole fraction of methanol = 1 - 0.312 = 0.688

Now put all the given values in the above formula, we get:

$P_{Mixture}=x_{CH_3OH}\times p^o_{CH_3OH}+x_{H_2O}\times p^o_{H_2O}$

$P_{Mixture}=0.688\times 256torr+0.312\times 55.3torr$

$P_{Mixture}=193.4torr$

From this we conclude that the total vapor pressure of mixture is less than the total given vapor pressure of 211 torr. That means, the interactions between the methanol and water would be weaker than those between the individual substances. So, this is not an ideal mixture.

Hence, this is not an ideal mixture.

Which of the following has the largest number of molecules? a 1 g of benzene, C6H6 b 1 g of formaldehyde, CH2O c 1 g of TNT, C7H

Pachacha [2.7K]

Answer: 1g of formaldehyde

Explanation:

Molar Mass of benzene (C6H6) = (12x6) + (6x1) = 78g/mol

1mole(78g) of benzene contains 6.02x10^23 molecules.

1g of benzene with contain = (6.02x10^23) /78 = 7.72x10^21 molecules

Molar Mass of formaldehyde (CH2O) = 12 +2+16 = 30g/mol

1mole (30g) of formaldehyde contains 6.02x10^23 molecules.

1g of formaldehyde will contain = (6.02x10^23) /30 = 2.01x10^22 molecules

Molar Mass of TNT(C7H5N3O6) = (12x7)+(5x1)+(14x3)+(16x6) = 227g/mol

1mole(227g) of TNT contains 6.02x10^23 molecules.

1g of TNT will contain = (6.02x10^23)/227 = 2.65x10^21 molecules

Molar Mass of naphthalene (C10H8) = (12x10) +8 =128g/mol

1mole(128g) of naphthalene contains 6.02x10^23 molecules.

1g of naphthalene will contain = (6.02x10^23)/128 = 4.7x10^21 molecules

Molar Mass of glucose(C6H12O6) = (12x6) + 12 +(16x6) = 180g/mol

1mole(180g) of glucose contains 6.02x10^23 molecules.

1g of glucose will contain = (6.02x10^23)/180 = 3.34x10^21 molecules

Therefore, 1g of each of the compound contains the following:

Benzene = 7.72x10^21 molecules

Formaldehyde = 2.01x10^22 molecules

TNT = 2.65x10^21 molecules

Naphthalene = 4.7x10^21 molecules

Glucose = 3.34x10^21 molecules

From the above, we see clearly that formaldehyde has the largest number of molecules
