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%?

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:

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

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

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

the answer is definitely c.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
