The following reaction produces ethanoic acid (CHACOOH) from methanol (CH3OH) and carbon
monoxide
CHCOOH
CH3OH + CO
Relative atomie mass: H = 1:0 = 16; C = 12
Calculate the maximum mass of ethanoic acid that can be produced from 160g methanol,
assuming the carbon monoxide is in excess.

Answer:

[tex]\boxed{\text{300 g}}[/tex]

Explanation:

We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

M_r:         32                          60

           CH₃OH + CO ⟶ CH₃COOH

m/g:        160

(a) Moles of CH₃OH

[tex]\text{Moles of CH$_{3}$OH} = \text{160 g CH$_{3}$OH }\times \dfrac{\text{1 mol CH$_{3}$OH }}{\text{32 g CH$_{3}$OH}}= \text{5.00 mol CH$_{3}$OH}[/tex]

(b) Moles of CH₃COOH

[tex]\text{Moles of CH$_{3}$COOH} = \text{5.00 mol CH$_{3}$OH } \times \dfrac{\text{1 mol CH$_{3}$COOH}}{\text{1 mol CH$_{3}$OH }} = \text{5.00 mol CH$_{3}$COOH}[/tex]

(c) Mass of CH₃COOH

[tex]\text{Mass of CH$_{3}$COOH} =\text{5.00 mol CH$_{3}$COOH} \times \dfrac{\text{60 g CH$_{3}$COOH}}{\text{1 mol CH$_{3}$COOH}} = \textbf{300 g CH$_{3}$COOH}\\\\\text{The maximum mass of ethanoic acid that can be produced is $\boxed{\textbf{300 g}}$}[/tex]
