Question

39 БАЛЛОВ! СРОЧНО Вычислите объём метана,входящий в состав природного газа объёмом 30л. Состав природного газа CH4 метан-90%,C2H6 этан-4%,другие газы -6

Answer 1

V(CH4)=V(природного газа) * w(CH4)
V(CH4)=30*0.9=27л
Ответ: 27л

Answer 2

Calculation of Methane Volume in Natural Gas

To calculate the volume of methane in natural gas, we need to consider the composition of the natural gas and the volume of the gas. In this case, the natural gas has a volume of 30 liters and consists of methane (CH4) at 90%, ethane (C2H6) at 4%, and other gases at 6%.

To find the volume of methane in the natural gas, we can use the following steps:

1. Calculate the volume of methane: - Multiply the total volume of natural gas (30 liters) by the percentage of methane (90% or 0.9): ``` Volume of methane = 30 liters * 0.9 = 27 liters ```

Therefore, the volume of methane in the natural gas sample is 27 liters.

Please note that the calculation assumes that the percentages provided represent the volume percentages of the gases in the natural gas sample.
