The number of protons in an uncharged atom equals the number of electrons.
Aww man, I love these types of problems!!!
So, it's a simple formula:
P1*V1/T1=P2*V2/T2
In this case, we remove V(volume) as there is none listed, leaving this:
P1/T1=P2=T2
Think you got it from here? All you gotta do is plug in the numbers and solve
If you have any further problems, just let me know!!
0,15 moles of NaOH-------in------------1000ml
x moles of NaOH------------in--------100ml
x = 0,015 moles of NaOH
final volume = 150ml
0,015 moles of NaOH---in-------150ml
x moles of NaOH--------------in-----1000ml
x = 0,1 moles of NaOH
answer: 0,1mol/dm³ (molarity)
862^-10 my friend this is the answer
