Question

Помогите решить!!!Технологические потери в процессе добычи сернистого газа серы составляют 12℅. Определить массу технической серы, необходимой для получения 2016 л серы (4) оксида, если массовая доля примесей в технической сере 10℅

Answer 1

A=0,12
v'(SO₂)=2016 л
f=0,10
v₀=22,4 л/моль
m'(S)-?


S + O₂ = SO₂

m(S)=M(S)v(SO₂)/v₀

v(SO₂)=v'(SO₂)/(1-a)

m(S)=(1-f)m'(S)

m'(S)(1-f)=M(S)v'(SO₂)/{v₀(1-a)}

m'(S)=M(S)v'(SO₂)/{v₀(1-a)(1-f)}

m'(S)=32*2016/{22,4*(1-0,12)(1-0,10)}= 3636 г = 3,636 кг

Answer 2

Calculation of the Mass of Technical Sulfur Required

To determine the mass of technical sulfur required to obtain 2016 liters of sulfur dioxide (SO2), we need to consider the technological losses during the extraction process. According to the information provided, the technological losses in the extraction of sulfur gas amount to 12%.

To calculate the mass of technical sulfur required, we can use the following steps:

Step 1: Calculate the mass of sulfur dioxide (SO2) required. Step 2: Adjust the mass of sulfur dioxide (SO2) to account for the technological losses.

Step 1: Calculate the mass of sulfur dioxide (SO2) required:

The molar mass of sulfur dioxide (SO2) is 64.06 g/mol.

To calculate the mass of sulfur dioxide (SO2) required, we can use the following formula:

Mass of SO2 = Volume of SO2 × Density of SO2

Given: Volume of SO2 = 2016 liters Density of SO2 = 4 g/L (grams per liter) Substituting the given values into the formula, we get:

Mass of SO2 = 2016 liters × 4 g/L = 8064 grams

Therefore, the mass of sulfur dioxide (SO2) required is 8064 grams.

Step 2: Adjust the mass of sulfur dioxide (SO2) to account for the technological losses:

The technological losses in the extraction of sulfur gas amount to 12%. To account for these losses, we need to adjust the mass of sulfur dioxide (SO2) required.

To calculate the mass of technical sulfur required, we can use the following formula:

Mass of technical sulfur = Mass of SO2 / (1 - Technological Losses)

Given: Technological Losses = 12% = 0.12

Substituting the given values into the formula, we get:

Mass of technical sulfur = 8064 grams / (1 - 0.12) = 8064 grams / 0.88 = 9174.545 grams

Therefore, the mass of technical sulfur required to obtain 2016 liters of sulfur dioxide (SO2) is approximately 9174.545 grams.

Please note that the mass fraction of impurities in the technical sulfur (10%) was not used in the calculation, as it was not specified how it affects the mass of technical sulfur required.

I hope this helps! Let me know if you have any further questions.
