Question

in a sampla of sodiumchloride the percentage of chloride is 45.5 sodium chloride​

Answer 1

Answer:

The molecular mass of pure sodium chloride (Nacl)=

At mass of Na+At mass of chloride

⇒(23+35.5)

⇒58.5

% of chlorine in pure Nacl=35.5/58.4×100= 60.6

Thus % of purity of Nacl in the sample=45.5/60.6×100⇒75

Answer 2

Answer:

to prove : molecular mass of sodium chloride

Explanation:

atm of sodium : 23

atm of chloride: 35.5

add all : ( 23. + 35.5)

ans : 58.5

chlorine percentage in sodium chloride is. : 35.5 / 58 . 5 * 100.

Ans : 60.6 percent.

purity percentage of sodium chloride : 45.5 /60.6 * 100.

Ans : 75 precent

therefore the purity of Na Cl is 75 precent and chlorine percentage is 60.6.
