Question

Смешали 45литров азота 15 литров кислорода и 60 литров угликислого газа Опредилите объёмные доли газовв полученой смеси

Answer 1

Φ(N2)=45 л/120 л*100 =37,5%
φ(O2)=15 л/120 л*100 =12,5%
φ(CO2)=100-37,5-12,5=50%
120 л- это объем всей смеси

Answer 2

объем всей смеси  45л+15л+6л = 120л

Объемная доля азота  45лх100% /120л =37.5 %

объемная доля кислорода 15лх100% / 120л =12.5%

объемная доля углекислого газа 60лх100/120л= 50%

Answer 3

Calculation of Volume Fractions of Gases in the Mixture

To determine the volume fractions of gases in the given mixture, we need to calculate the volume of each gas relative to the total volume of the mixture.

Given: - Nitrogen volume: 45 liters - Oxygen volume: 15 liters - Carbon dioxide volume: 60 liters

Total volume of the mixture = Nitrogen volume + Oxygen volume + Carbon dioxide volume

Let's calculate the total volume of the mixture:

Total volume = 45 liters + 15 liters + 60 liters = 120 liters

Now, we can calculate the volume fractions of each gas in the mixture:

Volume fraction of Nitrogen = (Volume of Nitrogen / Total volume) * 100 Volume fraction of Oxygen = (Volume of Oxygen / Total volume) * 100 Volume fraction of Carbon dioxide = (Volume of Carbon dioxide / Total volume) * 100

Let's calculate the volume fractions:

Volume fraction of Nitrogen = (45 liters / 120 liters) * 100 = 37.5% Volume fraction of Oxygen = (15 liters / 120 liters) * 100 = 12.5% Volume fraction of Carbon dioxide = (60 liters / 120 liters) * 100 = 50%

Therefore, the volume fractions of gases in the given mixture are approximately: - Nitrogen: 37.5% - Oxygen: 12.5% - Carbon dioxide: 50%

Please note that these calculations are approximate and may vary slightly depending on the exact values used.
