For an irregularly shaped objects, we use a GRADUATED CYLINDER to determine its volume by water displacement method. We fill the glassware first with water then measure the volume. Next, drop the object and read off the new volume. Calculate the difference between the volumes.
PV = nRT
Pressure times volume = number of moles times ideal gas constant times temperature
50mL = .05L
1 atm (.05) = n (.0821) (273)
.05 = n (22.4133)
.022 = n (number of moles)
6.022E23 molecules = 1 mole
.022 x 6.022E23 = 1.325E23 molecules
Cool dry air meeting warm Moist air
Hello there!
The correct answer is B. Electrons will be added to an atom starting from the lowest possible level or sublevel.
Hope This Helps You!
Good Luck :)
