Answer:
11.19 %
Explanation:
1 molecule water = 2 H + 1 O
If H = 1.008 u and O = 16.00 u, then
Water = 2H + 1 O = (2 × 1.008 u) + (1 × 16.00 u) = 2.016 u + 16.00 u = 18.02 u
The formula for mass percent is
So,
Hello!
The dissociation reaction of HNO₃ is the following:
HNO₃ → H⁺ + NO₃⁻
This is a strong acid, so the concentration of HNO₃ would be the same as the concentration of H⁺. The formula for pH is the following:
![pH=-log([H_3O^{+}])=-log(0,75M)=0,12](https://tex.z-dn.net/?f=pH%3D-log%28%5BH_3O%5E%7B%2B%7D%5D%29%3D-log%280%2C75M%29%3D0%2C12)
So, the pH would be 0,12
Have a nice day!
