Which of the following are correct? electrons generally occupy the lowest energy orbital first. the c atom has two unpaired electrons. the he atom has two electrons that have parallel spin in its 1s orbital. the arrangement of the orbitals is the same in a multielectron atom and a single-electron atom. in the li atom, the 3s, 3p, and 3d orbitals have different energies. the he atom has one electron each in 1s and 2s orbitals.

Explanation:

no but i do not usually comment or use my voice that much when it comes to social media

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
