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.

On weekends, I usually take the opportunity to relax and recharge after a long week of work. My typical weekend starts with a slow and peaceful morning. I like to sleep in a bit and then enjoy a leisurely breakfast at home. After that, I often engage in some light exercise, such as going for a jog or practicing yoga. In the afternoon, I like to spend time pursuing my hobbies and interests. I am an avid reader, so I usually curl up with a good book or catch up on the latest articles online. I also enjoy cooking, so I often experiment with new recipes or prepare a special meal for myself or my family. In the evening, I like to socialize and spend time with my loved ones. I may meet up with friends for dinner or have a cozy movie night at home with my partner. Sometimes, I also use this time to catch up on household chores or run errands that I couldn't get to during the week. Overall, my weekends are a time for me to unwind, indulge in my passions, and connect with the important people in my life. It's a time to recharge and prepare myself for the upcoming week. I cherish these moments and always look forward to the next weekend.

On weekends, I like to take a break from the hustle and bustle of the week and enjoy some quality time for myself. My weekend routine usually starts with a lazy morning, where I can sleep in and wake up naturally without the sound of an alarm clock.

After having a leisurely breakfast, I often engage in activities that I enjoy. One of my favorite pastimes is reading, so I like to curl up on my couch with a good book and immerse myself in its captivating world. It's a great way for me to relax and escape from reality for a while.

In the afternoon, I like to get outside and enjoy some fresh air. Depending on the weather, I might go for a hike in a nearby park or take a stroll along the beach. Being in nature rejuvenates my mind and allows me to appreciate the beauty of the world around me.

Evenings are usually reserved for spending time with friends or family. We might gather for a delicious home-cooked meal or go out to try a new restaurant in town. It's always wonderful to catch up with loved ones and share laughter and stories.

Before the day comes to an end, I like to reflect on the week that has passed and set some goals for the upcoming week. This helps me stay focused and motivated for the days ahead.

Overall, my weekends are a perfect balance of relaxation, rejuvenation, and quality time with loved ones. It's a time for me to recharge and prepare for the week ahead,
