What is the percentage composition of NaCl?

Answer 1

Calculate the percent by weight of sodium (Na) and chlorine (Cl) in sodium chloride (NaCl) * Calculate the molecular mass (MM):

MM = 22.99 + 35.45 = 58.44 * Calculate the total mass of Na present:

1 Na is present in the formula, mass = 22.99 * Calculate the percent by weight of Na in NaCl:

%Na = (mass Na ÷ MM) x 100 = (22.99 ÷ 58.44) x 100 = 39.34% * Calculate the total mass of Cl present:

1 Cl is present in the formula, mass = 35.45 * Calculate the percent by weight of Cl in NaCl:

%Cl = (mass Cl ÷ MM) x 100 = (35.45 ÷ 58.44) x 100 = 60.66% The answers above are probably correct if %Na + %Cl = 100, that is,

39.34 + 60.66 = 100.

Answer 2

Calculating the percentage of sodium in sodium chloride by weight:

In order to calculate the percentage of sodium in sodium chloride, you need to know the RAM (Relative Atomic Mass) of sodium and the RMM (Relative Molecular Mass) of sodium chloride.

RAM Na=23g

RMM NaCl=58.5g

Using the formula RAM/RMM * 100%, you get

23/58.8 * 100 =39.3%

Answer 3

The gram atomic mass of sodium is 22.9898; the gram atomic mass of chlorine is 35.453. Therefore, the percent by mass of sodium in NaCl is 100[22.9898/(22.9898 + 35.453)] or 39.337 %, to the justified number of significant digits. The percentage of chlorine is the remainder from 100.00% or 60.663 %.

Answer 4

These percentages are:

- chlorine: 60,334 %

- sodium: 39,666 %

Answer 5

Sodium chloride contain 60,334 17 % chlorine.

Answer 6

The percentage composition of Na in NaCl is 23 / 58.44 = 0.394 or 39.4%

Answer 7

The percentage of sodium in sodium chloride is 39,666 %.

Answer 8

Sodium chloride contain 39,665 % sodium and 60,335 % chlorine.

Answer 9

Sodium chloride contain 39,666 % sodium.
