I want to know if x ray is better than gamma ray in killing cancerous tumor in the body and why
I am doing triprotic acid titrations.
I have an imaginary acid (H3A) 10mL with the concentration 0.760M and we are titrating a NaOH with the concentration of 0.320M.
I have to find the amount of NaOH in mol and mL for
1. first half-equivalence point
2.first equivalence point
3. second-half equivalence point
4.second equivalence point
5. third half-equivalence point and
6. third equivalence point.
and then I have to find the pH for each of these points.

High concentrations of ammonia (NH3), nitrite ion and nitrate ion in water can kill fish. Lethal concentration of these species for rainbow trout are 1.1 mg/L, 0.40 mg/L, and 1361 mg/L, respectively. Express these concentrations in molality units, assuming a solution density of 1.00 g/mL.
