Question

Answer 1

Câu 31: C

Câu 32: C

Có: \(n_{CH_3COONa}=n_{CH_3COOC_2H_5}=0,1\left(mol\right)\)

\(\Rightarrow m_{CH_3COONa}=0,1.82=8,2\left(g\right)\)

Answer 2

1-C

2-\(CH_3COOC_2H_5+NaOH\rightarrow CH_3COONa+C_2H_5OH\\ n_{CH_3COONa}=n_{CH_3COOC_2H_5}=0,1\left(mol\right)\\ \Rightarrow m_{CH_3COONa}=0,1.82=8,2\left(g\right)\\ \Rightarrow ChọnC\)
