119 (atomic mass)- 50 protons= 69 neutrons
density of acetone in gm/cm^3 is 0.791
=28.80cm^3*0.791 g/cm63
=22.78 g
A= mass number = number of protons and neutrons in the nucleus
Z= number of electrons = number of protons
Given, number of neutrons= 30
Z = A - 30 = 70 - 30 = 40
Z = 40
I hope I was helpful
Answer:
A
Explanation:
OH is generally basic, while H is generally acidic so the greater the OH concentration, the more basic the solution will be.
