C. 0.5
This is the answer.
(assuming that the D option is 1, if it is 0.1 then the answer is 0.1)
To be able to calculate the number of moles for this problem, for simplicity, we assume that it is an ideal gas. We use the equation PV = nRT. We do as follows:
PV = nRT
n = PV / RT
n = 1(100000) / 0.08206 (27 + 273.15)
n = 4060.04 mol
The total pressure of the mixture of gases is
equal to the sum of the pressure of each gas as if it is alone in the
container. The partial pressure of a component of the mixture is said to be
equal to the product of the total pressure and the mole fraction of the
component in the mixture.<span>
Partial pressure of hydrogen gas = 1.24 atm x
.25 = 0.31 atm
<span>Partial pressure of the remaining = 1.24 atm x
(1-.25) = 0.93 atm </span></span>
The correct answer is the gamma ray. It has the most penetration power and will pass through a number of things. Also, a gamma ray has shorter wavelength therefore higher energy from the equation, Energy = hc/wavelength.
