Để giải bài toán này, ta cần xác định công thức hóa học của chất rắn Y và muối trung hòa trong dung dịch Z.
Gọi số mol của MgCO3 trong hỗn hợp X là n1, số mol của RCO3 trong hỗn hợp X là n2.
Theo đề bài, ta có:
Khối lượng của MgCO3 trong hỗn hợp X là: m1 = n1 * MM(MgCO3)
Khối lượng của RCO3 trong hỗn hợp X là: m2 = n2 * MM(RCO3)
Vì các phản ứng xảy ra hoàn toàn nên ta có:
n1 mol MgCO3 + n2 mol RCO3 + H2SO4 → Y + Z
Theo đề bài, khối lượng rắn Y thu được là 23,3 gam, vậy ta có:
m1 + m2 = 23,3
Theo đề bài, dung dịch Z chứa m gam bạc trung hòa, vậy ta có:
m = m1 + m2
Ta có công thức hóa học của trung hòa trong dung dịch Z là:
Z = MgSO4 + R2SO4
Do đó ta có hệ thống phương tiện:
m1 + m2 = 23,3
m = m1 + m2
This method system, ta has:
m1 = 23,3 - m2
m = 23,3 - m2 + m2 = 23,3
Vậy m = 23,3 gam.
