The solvent in the mixture is the ethyl alcohol assuming that the ethyl alcohol is not very dilute. The amount of the solvent must be greater than the amount of the solute. If the ethyl alcohol is dilute such that the resulting solution will have more water than pure ethyl alcohol, the solvent is water and the solute is ethyl alcohol.

Answer:

Ethyl alcohol is a solvent on the mixture.

Explanation:

Solution: It is a mixture of liquid in which solute (minor component) is distributed uniformly in a solvent (major component).

In a solution, mass of solute is always less than the mass of solvent.

Mass of water = 150 mL

Mass of ethyl alcohol = 600 mL

Mass of water < Mass of ethyl alcohol

Ethyl alcohol is a solvent on the mixture.

Estimate the standard internal energy of formation of liquid methyl acetate (methyl ethanoate, ch3cooch3) at 298 k from its stan
LenKa [72]

solution:

the reaction for formation of methyl acetate is\\CH_{3}OH+CH_{3}COOH----------->CH_{3}COOCH_{3}+H_{2}O\\standard internal energy \\\delta u=\delta H -\delta(pv)=\delta H -\delta n\times RT\\where \delta n=change in number of moles=0\\\delta u=\delta H\\=-442kj/mol

The substrate is the same in parts a and b, however the mechanism that proceeds is different. Explain how the choice of solvent
GenaCL600 [577]

Answer:

See explanation

Explanation:

The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.

Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.

However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.

A particular oral contraceptive contains 0.038 mg of ethinyl estradiol in each pill. The formula of this compound is C20H24O2. H
Ray Of Light [21]

<u>Answer:</u> The number of molecules of ethinyl estradiol present in one pill are 7.71\times 10^{16}

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of ethinyl estradiol = 0.038 mg = 3.8\times 10^-5}g    (Conversion factor: 1 g = 1000 mg)

Molar mass of ethinyl estradiol (C_{20}H_{24}O_2)=[(20\times 12)+(24\times 1)+(2\times 16)]=296g/mol

Putting values in above equation, we get:

\text{Moles of ethinyl estradiol}=\frac{3.8\times 10^{-5}g}{296g/mol}=1.28\times 10^{-7}mol

According to mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of molecules

So, 1.28\times 10^{-7}mol of ethinyl estradiol will contain = (1.28\times 10^{-7}\times 6.022\times 10^{23})=7.71\times 10^{16} number of molecules

Hence, the number of molecules of ethinyl estradiol present in one pill are 7.71\times 10^{16}
