Cho 200 g dung dịch NaCl 0,5M tác dụng hết với 400 ml AgNO3. Sau phản ứng thu được kết tủa và dung dịch không màu
ivolga24 [154]

Answer:

Explanation:

a. NaCl+ AgNO3-----> NaNO3+ AgCl

b. Số mol của NaCl= 0,2*0,5= 0,1 (mol)

------> Số mol của kết tủa AgCl tạo thành= 0,1 mol (dựa vào phương trình hóa học)

-----> Khối lượng của kết tủa AgCl tạo thành= 0,1*143,5=14,35(g)

c. Số mol của AgNO3= số mol của NaCl= 0,1 (mol)

------> Nồng độ mol của dd AgNO3 đã tham gia phản ứng= \frac{0,1}{0,4}=0,25(M)

PLEASE HELP: You have been given 2.42 moles of beryllium sulfide (BeS), determine the mass in grams of beryllium sulfide that yo
Alecsey [184]

The mass in grams of the given beryllium sulfide is 99.2 g. The correct option is the second option - 99.2 g BeS

<h3>Calculating mass of a compound </h3>

From the question, we are to determine the mass of the given beryllium sulfide.

From the given information,

Number of moles of beryllium sulfide (BeS) given = 2.42 moles

Using the formula,

Mass = Number of moles × Molar mass

Molar mass of BeS = 41 g/mol

Then,

Mass of BeS = 2.42 × 41

Mass of BeS = 99.22

Mass of BeS ≅ 99.2 g

Hence, the mass in grams of the given beryllium sulfide is 99.2 g. The correct option is the second option - 99.2 g BeS
