Question

Одне з родовищ природного газу містить 95,02 % метану, 2,25 % етану, 0,73 % пропану і 0,05 % бутану. Який об'єм метану міститься у 40000 м³ природного газу?

Answer 1

Ответ:

994,4 г

Объяснение:

CH4+Cl→CH3Cl+HCl
n=V/Vm
n=421,12 л=18,7 моль
m=n*M
M(CH3Cl)=12+3+35,5=50,5 г/моль
m=18,7+50,5=944,4г

Answer 2

Calculating the Volume of Methane in Natural Gas

To calculate the volume of methane in 40,000 m³ of natural gas, we can use the percentage of methane in the given composition of natural gas.

The composition of the natural gas is as follows: - Methane: 95.02% - Ethane: 2.25% - Propane: 0.73% - Butane: 0.05%

Calculation

To find the volume of methane in 40,000 m³ of natural gas, we can use the percentage of methane in the composition.

Step 1: Calculate the volume of methane in 40,000 m³ of natural gas.

Step 2: Use the percentage of methane in the composition to find the volume of methane.

Solution

Step 1: Calculate the volume of methane in 40,000 m³ of natural gas. - Volume of methane = (Percentage of methane / 100) * Total volume of natural gas - Volume of methane = (95.02 / 100) * 40,000 m³ - Volume of methane = 0.9502 * 40,000 m³ - Volume of methane = 38,008 m³

Step 2: Use the percentage of methane in the composition to find the volume of methane. - Therefore, 40,000 m³ of natural gas contains 38,008 m³ of methane.

Answer

40,000 m³ of natural gas contains 38,008 m³ of methane.
