Respuesta :
12.28 L volume at 6.98atm in sample gas occupies 10. 28 l at 8. 34atm. Hence, option A is correct.
What is ideal gas?
Ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, and which consequently obeys the gas laws exactly.
In the limit of low pressures and high temperatures, where the molecules of the gas move almost independently of one another, all gases obey an equation of state known as the ideal gas law:
PV = nRT,
- P is pressure of gas (atm)
- T is temperature of gas (K)
- where n is the number of moles of the gas
- R is the universal gas constant, 8.3145 joules/K.
When Temperature is constant so, it follow Boyle's law:
P1 V1 = P2 V2
P1 = 8.34atm, V1 = 10.28 L, P2 = 6.98atm
V2 = P1 V1 / P2
V2 = 8.34atm x 10.28 / 6.98atm
V2 = 12.28 L
12.28 L volume at 6.98atm in sample gas occupies 10. 28 l at 8. 34atm. Hence, option A is correct.
