in a neutralization reaction, sodium carbonate solution was dissolved in water and the solution made to 250cm,25cm of this solution neutralized 20cm of 0.25M nitric acid . calculate the mass of carbonate that was dissolved in water​

your answers are a,b,,e and f

i hope this

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
