Citric acid, C6H8O7, a component of jams, jells and fruity soft drinks, is prepared industrially via a fermentation of sucrose by the moid Aspergillus niger. The equation representing this raction id :
C12H22O11 + H2O + 3O2 ? 2C6H8O7 +H2O
what mass of nitric acid is produced from exactly 1 metric on(1000 x 103 kg) of sucrose if the yield is 92.30%?

Respuesta :

Answer:

1.04 tonnes

Explanation:

As we have the equation balanced, we need to know, form the percent yield and the theoretical yield, the actual yield:

[tex]\% yield=\frac{actual}{theoretical} *100\\\\actual=\frac{\% yield*theoretical}{100} \\\\actual=\frac{92.30*2}{100} \\\\actual=1.846[/tex]

With this, we need to convert the mass of sucrose into moles:

[tex]M_{sucrose}=342.3g/mole\\m_{sucrose}=10^{6}g\\n_{sucrose}=2921.41 moles[/tex]

Now, with the yield, we apply the rule of three, with the actual yield, to know the moles of citric acid produced:

[tex]1mole\longrightarrow 1.846mole\\2921.41mole \longrightarrow x\\\\x=2921.41*1.846=5392.93mole[/tex]

Therefore, 5392.93 moles of citric acid are produced, now we need to know the mass:

[tex]M_{citric}=192.12g/mole\\n_{citric}=5392.93mole\\m_{citric}=1.04x10^{6}g\\m_{citric}=1.04tonnes[/tex]
