An enclosed containe9r5tts-t19rvvhq+b 2ow u8vyr with an internav +cdvyej28;)xp aw;2ht 9y whl volume $V$ contains $3.0\times {10}^{2}3$ helium atoms at a Kelvin temperature $T$. What is the pressure of the helium gas?

A. $(3.0\times {10}^{23})\frac{RT}{V}$
B. $3.0\frac{k_{B}T}{V}$
C. $\frac{3.0}{6.02}\frac{RT}{V}$
D. $\frac{3.0}{6.02}\frac{k_{B}T}{V}$


参考答案:  C


本题详细解析:
Explanation:

Apply $PV=nRT$, in which $n$ is the number of moles of gas molecules. Using

$n$=$\frac{N}{N_A}$=$\frac{3.0}{6.02}$arrives at the solution.
