Use the General Gas Law
PV = nRT => n = PV/ RT
P= <span>10130.0 kPa
V= </span><span>50 L
R= </span><span>R = 8.314 L∙kPa/K∙mol
T= </span><span>300°C + 273 = 573 K
n = </span>10130.0 kPa 50 L / 8.314 L∙kPa/K∙mol <span>573 K
n = </span><span>106.32 mol</span>

Answer:
When combined with Hubble's visible-light data, astronomers can ... Dark things absorb light, but this invisible stuff neither absorbs, nor ... Is dark matter made of still undiscovered tiny particles, as most physicists suppose?
Explanation:
J.J. Thomson hypothesized and discovered that the atom was not the smallest unit of matter but that instead there were much smaller units. He discovered "sub-atomic particles" which make up atoms. The sub-atomic particle that Thomson discovered was the electron. He discovered this through a process of experiments testing cathode rays.
