Combustion analysis of toluene, a common organic solvent, gives 8.20 mg of co2 and 1.92 mg of h2o. if the compound contains only
cestrela7 [59]
For the purpose of proper representation in this item, we let the number of moles of carbon in the compound be x, that of H is y. The equation of toluene now becomes,
                   CxHy
The combustion reaction is,
        CxHy + O2 --> CO2 + H2O

The equation presented above may not be balanced yet. Then, we determine the number of mmols of C, H, and O in the product using the given masses.
    
(1) 8.20 mg CO2
             (8.2 mg CO2)(1 mmol CO2/44 mg CO2) = 0.186 mmol CO2
     which means,
                     0.186 mmol C
                     0.373 mmol O

(2) 1.92 mg H2O
            (1.92 mg H2O)(1 mmol H2O/18 mg H2O) = 0.107 mmol H2O
    which means
                    0.2133 mmol H
                    0.107 mmol O

Thus, the equation for toluene is,
               C(0.186)H(0.2133)

Dividing the numbers by the lesser value,
               CH(8/7)
To eliminate the fraction, we multiply by the denominator. Thus, the final answer would be,
             <em> C7H8</em>

When 2.0 mol of methanol is dissolved in 45 grams of water, what is the mole fraction of methanol
kaheart [24]

The mole fraction of methanol in the mixture is 0.444

We'll begin by calculating the number of mole of water.

  • Mass of water = 45 g
  • Molar mass of water = 18 g/mol
  • Mole of water =?

Mole = mass / molar mass

Mole of water = 45 / 18

Mole of water = 2.5 moles

Finally, we shall determine the mole fraction of methanol.

  • Mole of water = 2.5 moles
  • Mole of methanol = 2 moles
  • Total mole = 2 + 2.5 = 4.5 moles

Mole fraction of methanol =?

Mole fraction = mole / total mole

Mole fraction of methanol = 2 / 4.5

Mole fraction of methanol = 0.444

Thus, the mole fraction of methanol is 0.444
