Answer:
yes I do think they mean the same thing
Explanation:
150 grams and 150 grams is the same thing and adding 0 to the end of a decimal does not change its value, you could even put 150.0000000 grams and it would still be equivalent to the other numbers
This assumption is not valid because, there are some elements which exist in two or more forms; they have the same atomic number but differ in their mass number, which meas that they possess different number of neutrons. These type of element are called isotopes. Isotope have the same atomic number and similar physical and chemical properties but they have different number of neutrons and therefore possess different masses.

The given acid is HCOOH, it is dissociated in water. This balanced equation represents the dissociation of HCOOH in water:
HCOOH + H2O ---> H+ + COOH-
The Ka of HCOOH is:
Ka = concentration of products / concentration of reactants
Ka = [COOH-] [H+] / [HCOOH]
