Hi I think I might know the answer to your question it is pretty tricky though!
Chlorine Gas = 70.8 grams/moles
Moles of Chlorine Gas = 57.8/70.8 = 0.816 mol
Volume Gas at STP = 22.4 L/mol
Volume of Chlorine Gas = .816*22.4=18.22 Litters
I hoped that helps if not so sorry!
<span>When ammonium is dissolved in wated, we have,
NH3 + H2O >> NH4+ + OHÂŻ
pOH = -log[OH-]
pOH = -log[2.25x10^-2]
pOH = 1.6478
Since pH + pOH=14. Therefore pH = 14 - pOH = 14 - 1.648 = 12.3522.
[H+]=10^-pH
[H+]=10^(-12.3522)
[H+]= 4.3250 * 10 ^(-5)</span>
Atomic radius of copper atom (r)= 128 pm
volume of sphere = 4/3 * pi * r^3 = 4/3 * 3.14 * 128^3
volume = 8780076.373 pm^3
