The common laboratory solvent ethanol is often used to purify substances dissolved in it. The vapor pressure of ethanol , CH3CH2
OverLord2011 [107]

Answer:

Molar mass of solute is 183.4g/mol

Explanation:

Using Raoult's law it is possible to find moles of solute, thus:

P_{solution} = X_{solvent}P_{solvent}^0

Where pressure of solution is 53.15 mmHg, pressure of pure solvent is 54.68 mmHg and mole fraction is:

53.15 mmHg = X 54.68 mmHg

<em>0.9720 = X</em>

<em />

Mole fraction of solvent is defined as moles of solvent / total moles.

Moles of solvent are:

286.8g × (1mol / 46.07g) = 6.225 moles of ethanol.

That is:

0.9720 = \frac{6.225mol}{Y+6.225mol}

<em>Where Y are moles of solute.</em>

6.051 + 0.9720Y = 6.225

0.9720Y = 0.174

Y = 0.179 moles of solute

As mass of solute dissolved was 32.83g. Molar mass of solute is:

32.83g / 0.179mol = <em>183.4g/mol</em>

Answer:

3. 116.5 V

4. 119.6 V

Explanation:

3. Determination of the voltage.

Resistance (R) = 25 Ω

Current (I) = 4.66 A

Voltage (V) =?

V = IR

V = 4.66 × 25

V = 116.5 V

Thus, the voltage is 116.5 V

4. Determination of the voltage.

Current (I) = 9.80 A

Resistance (R) = 12.2 Ω

Voltage (V) =?

V = IR

V = 9.80 × 12.2

V = 119.6 V

Thus, the voltage is 119.6 V

Potassium hydroxide is classified as an arrhenius base because koh contains
mixas84 [53]

Answer: hydroxide ions

Explanation:

According to the Arrhenius concept, an acid is a substance that ionizes in the water to give hydronium ion or hydrogen ion  and a bases is a substance that ionizes in the water to give hydroxide ion .

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

As KOH can give hydroxide ions on dissociation , it is considered as arrhenius base.

KOH\rightarrow K^++OH^-
