Answer:
0.02325 m^3
Explanation:
P1 = 100000Pa , v1 = 0.0279m^3
P2= 120000Pa . V2 = ?
as mass and temperature are constant using ratio method for Boyle'slaw
P2V2= P1V1
or V2= P1V1/P2
V2 = 100000×0.0279/120000
V2= 0.02325 m^3
If the atom is neutral, then the number of electrons will ALWAYS be the same as the number of protons (which is the atomic number), so in this case the number of protons is 16, and that make the number of electrons 16
