Question

Сколько граммов уксусной кислоты можно получить из 450 г ацетата натрия Срочно 100 баллов

Answer 1

Ответ:

329,4 грамма

Объяснение:

2СH3COONa + H2SO4 = 2CH3COOH + Na2SO4

n(СH3COONa)=450/82=5.49 моль

n(CH3COONa)=n(CH3COOH)

m(CH3COOH)=5.49*60=329,4 грамма

Answer 2

Calculating the Amount of Acetic Acid from Sodium Acetate

To calculate the amount of acetic acid that can be obtained from 450 grams of sodium acetate, we need to consider the stoichiometry of the reaction between sodium acetate and a strong acid, such as hydrochloric acid. The balanced chemical equation for this reaction is:

CH3COONa + HCl → CH3COOH + NaCl

From the balanced equation, we can see that 1 mole of sodium acetate (CH3COONa) reacts with 1 mole of hydrochloric acid (HCl) to produce 1 mole of acetic acid (CH3COOH) and 1 mole of sodium chloride (NaCl).

The molar mass of sodium acetate (CH3COONa) is approximately 82.03 g/mol, and the molar mass of acetic acid (CH3COOH) is approximately 60.05 g/mol.

Using this information, we can calculate the amount of acetic acid that can be obtained from 450 grams of sodium acetate.

Calculation

1. Calculate the number of moles of sodium acetate: - Number of moles = Mass / Molar mass - Number of moles = 450 g / 82.03 g/mol - Number of moles ≈ 5.49 moles

2. Since the reaction is 1:1, the number of moles of acetic acid produced will be the same as the number of moles of sodium acetate.

3. Calculate the mass of acetic acid produced: - Mass = Number of moles × Molar mass - Mass ≈ 5.49 moles × 60.05 g/mol - Mass ≈ 329.34 grams

Answer

From 450 grams of sodium acetate, approximately 329.34 grams of acetic acid can be obtained
