Giả sử CTHH của 2 muối là ACO3.

Có: m muối tăng = 9,94 - 6,2 = 3,74 (g)

\(\Rightarrow n_{ACO_3}=\dfrac{3,74}{71-60}=0,34\left(mol\right)=n_{CO_2}\)

\(\Rightarrow V_{CO_2}=0,34.22,4=7,616\left(l\right)\)

Bạn tham khảo nhé!

Ta có công thức nhanh khi cho muối cacbonat tác dụng với HCl sau : 

m muối clorua = m muối cacbonat  + nCO2.11

=> nCO2=0,34 (mol) 

=> \(V_{CO_2}=0,34.22,4=7,616\left(l\right)\)
