A mixture of ideal gases has the following composition by mass :
N2 O2 CO2 60% 30% 10%
If the universal gas constant is 8314 J/kmolK, the characteristic gas constant of the mixture (in J/kgK) is _______.
-
- 274.996
- 247.996
- 374.996
- 174.996
Correct Option: A
Gas constant of mixture,
| Rm = | ||
| Average molar mass |
| Rm = | ||
| Average molar mass |
| Average molar mass = | = 30.233 kg/kmol | |||||||
| + | + | |||||||
| 28 | 32 | 44 | ||||||
| Rm = | = 274.996 J/kg -K | |
| 30.233 |
