V C 2 H 5 OH = 50.4/100 = 2l

→  m C 2 H 5 OH  = 2.1000.0,8 = 1600g

Phương trình hóa học :

C 2 H 5 OH  +  O 2  →  CH 3 COOH +  H 2 O

46 gam     60 gam

1600 gam     x

x = 1600x60/46

Vì hiệu suất đạt 80% →  m CH 3 COOH  = 1600.60.80/(46.100) = 1669,6g

→ m giấm  = 1669,6/5 x 100 = 33392 (gam) = 33,392 kg

Đổi 10kg = 10000g

Ta có: \(n_{CH_3COOH\left(LT\right)}=\dfrac{10000.5\%}{92\%}=\dfrac{12500}{23}\left(mol\right)\)

PTHH:

V rượu =  57,5.12/100 = 6,9(lít) = 6900(cm3)

=> m rượu = 6900.0,8 = 5520(gam)

Theo PTHH :

n CH3COOH = n C2H5OH = 5520/46 = 120(mol)

m CH3COOH = 120.60 = 7200(gam)

b)

m dd giấm = 7200/4% = 180 000(gam)
