Answer:

CH2Cl2 mole fraction =  0.833

CH2Br2 mole fraction = 0.167

Explanation:

Step 1: Data given

Number of moles CH2Cl2 = 0.0300 moles

Number of moles CH2Br2 = 0.0500 moles

Temperature = 25 °C

Vapor pressure of pure CH2Cl2 = 133 torr

Vapor pressure of pure CH2Br2 = 11.4 torr

Step 2:  Calculate mol fraction  in solution

Mol fraction CH2Cl2 = 0.0300 moles / (0.0300 + 0.0700)

Mol fraction CH2Cl2 = 0.300

Mol fraction CH2Br2 = 0.0700 moles / (0.0300 + 0.0700)

Mol fraction CH2Br2 = 0.700

Step 3: Calculate partial pressure

Partial pressure CH2Cl2 = 133 torr * 0.300 = 39.9 torr

Partial pressure CH2Br = 11.4 torr * 0.700 =7.98 torr

Step 4: Calculate the total pressure

total pressure = 39.9 + 7.98 = 47.88 torr

Step 5: Calculate mol fraction

partial pressure / total pressure = mole fraction

CH2Cl2 mole fraction = 39.9 / 47.88 = 0.833

CH2Br2 mole fraction = 7.98 / 47.88 = 0.167

What caused wind to blow
Arlecino [84]

Answer:

Different atmospheric pressure. When there is a different atmospheric pressure, air moves from the higher pressure to the lower pressure area which results in what you call <u>WIND</u> but can result in various speeds and pressure.

Hope this helped and if it did, please give my answer a brainliest.

A sample of O2, under occupies 500ml at 25.0°C. What volume will the sample occupy at 0.0°C
NeX [460]

Answer:

458ml

Explanation:

According to charles law, $\frac{V_{1}}{T_{1}} =\frac{V_{2}}{T_{2}} $

Given values,

Volume occupied $V_{2}=500ml$

Temperature $T_{1}=25.0^{\circ}C=25+273=298K$

Second temperature $T_{2}=0.0^{\circ}C=273K$

Volume $V_{2}=?$

From charles law, $V_{2}=\frac{V_{1} \times T_{2}}{T_{1}}$ \\$=\frac{500 \times 273}{298}$\\$=458ml$

$\therefore$ Volume occupied by the oxygen at 0.0°C is 458ml
