I'm learning this so... protons and electrons are the same number. that's all I can tell you. I'm still learning it.
Hey there!
Atomic mass Bromine ( Br ) = 79.9 u
Therefore:
79.9 g Br --------------- 22.4 L ( at STP )
18.0 g Br --------------- volume ??
Volume Br = 18.0 * 22.4 / 79.9
Volume Br = 403.2 / 79.9
Volume Br = 5.046 L
hope this helps!
Evaporation is the process by which water changes from a liquid to a gas or vapor. ... Condensation, the opposite of evaporation, occurs when saturated air is cooled below the ... This does vary geographically, though.
