Given:
n = 12 moles of oxygen
T = 273 K, temperature
p = 75 kPa, pressure
Use the ideal gas law, given by

where
V = volume
R = 8.3145 J/(mol-K), the gas constant
Therefore,

Answer: 0.363 m³
Explanation:
Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds
