Question

Calculate the mass of the unredacted benzaldehyde in the synthesis of benzoic acid and benzyl alcohol
GPT 3.5
The balanced chemical equation for the synthesis of benzoic acid and benzyl alcohol from benzaldehyde is:

2C7H6O + 2K2Cr2O7 + 3H2SO4 → 2C6H5COOH + 2C6H5CH2OH + K2Cr2(SO4)3 + 4H2O

From the equation, we can see that for every 2 moles of benzaldehyde (C7H6O) used in the reaction, we get 2 moles of benzoic acid (C6H5COOH) and 2 moles of benzyl alcohol (C6H5CH2OH).

The molar mass of benzaldehyde is 106.12 g/mol.

Given that the molar ratio of benzaldehyde to benzoic acid and benzyl alcohol is 2:2, we can calculate the mass of benzaldehyde required for the reaction as follows:

Benzaldehyde = 2 moles x 106.12 g/mol = 212.24 g

Therefore, the mass of unreacted benzaldehyde required for the synthesis of benzoic acid and benzyl alcohol is 212.24 grams.
