Mass number is equal to the sum of number of neutrons (neutral subatomic particle) and number of protons (positively charge particle).
Mass number =
Now, atomic number is same as the number of protons i.e. atomic of nitrogen is 7 . Thus, number of protons is also equal to 7.
Therefore,
Mass number =
= 
Hence, mass number of nitrogen is equal to .
The balanced equation is,
OBz-(aq) + H2O(l) ---> HOBz(aq) + OH-(aq)
The equation for Kb is :
Kb = [HOBz][OH-]/[OBz]
<h3>What do we know about benzoate ion?</h3>
The conjugate base of benzoic acid, benzoate is the simplest member of the family of benzoates. It consists of a benzoic acid core with a proton missing to give it a charge of -1. It serves as a xenobiotic metabolite for humans as well as a metabolite for plants. It is a benzoic acid's conjugate base.

M of CH2O= 12+2+16=30 g/mol
So 30g/mol = 3.5 mol
=> 16g/mol*3.5 divide by 30 = 1.86 mol
I think
Answer : 69.44 mL
Explanation : Here we can use the formula as
Where we have the value of
= 0.0887 M
= 0.0224 M and
= 275 mL
So, substituting the above values in the given equation we get,
0.0887 X x = 275 X 0.0224
Therefore, x = 69.44 mL
So it will require 69.44 mL.
Answer: because they’re similar?
