The atomic number of carbon is 6. what is the mass number of a carbon atom with 5 neutrons?

Atomic number of carbon = Number of protons = 6

Mass number of carbon = Number of protons + neutrons

= 6 + 5 = 11

the ratio of the conjugate base to the acid required to attain the desired ph.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
