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.

Growing up, I have always had a knack for language. That is the reason why literature is my favorite subject. Literature brings me to various worlds, some are based on the reality, some are created by the humans’ mind. In my free time, I always read lots of books. Writing is also a favorite activity of mine. When I write, I get to have control over my story. I love literature and I hope I myself can write many good stories in the future.
