Since neon is a noble gas we can easily assume its behaviour to be an ideal gas. In ideal gases pressure is said to be inversely proportional to volume, at fixed temperature, this is Boyle's law.
Therefore we can use this law to state the following equation P1V1/T1 = P2V2/T2 in this case temperature is fixed therefore it can be eliminated, then, P1V1 = P2V2 standard pressure (P1) is 101 325 Pa V1 = 375 ml P2 = 90 000 Pa substituting these values, 101 325 Pa * 375 ml = 90 000 Pa * V2 V2 = 101 325 * 375 / 90 000 = 422.18 ml After rounding off the final answer is option A - 422 ml
The elemental classification for oxygen would be non-metal. It is located in period number 2 and group number 16. It has an atomic number of 8. At room temperature, it exists as a gas. Hope this answers the question. Have a nice day.
