Answer:
12.1; acidic
Explanation:
I'm assuming the hydrogen concentration is H+.
So, first we must find pH.
pH = -log[H+]
I simply just plugged in the concentration.
I get 1.9 as the pH. This means that the substance is very acidic since it has a low pH.
Now to find poH.
poH + pH = 14
I simply plugged in once again!
I get 12.1 as the poH. This also determines that the substance is very acidic since it has a high poH.
C decreases by a factor of 3
1. Calculate no. of moles by dividing mass given/molar mass
= 0.250 /283.8
2. Now multiply no. of moles with avogadro's no.
3. The answer indicates no. of total atoms..
