January 12, 2021 | education

| Let’s execute the solution:

1. We compose the equation according to the problem condition:

X g -? Y = 2 mol;

СН3СОН + Ag2O = CH3COOH + 2Ag – qualitative reaction for aldehyde, obtained acetic acid, silver;

2. Calculations:

M (C2H4O) = 44 g / mol;

M (CH3COOH) = 60 g / mol.

3. Determine the amount of the original substance:

Y (CH3COOH) = 2 mol;

Y (C2H4O) = 2 mol since the amount of substances is 1 mol according to the equation.

4. Find the mass of the aldehyde:

m (C2H4O) = 2 * 44 = 88 g.

Answer: to carry out the process, acetaldehyde weighing 88 g is required.
