calculate the concentration (% m/m) of nacl solution that was made by dissolving 40.0 g of sodium chloride in enough water to make 500.0 g of solution g.

Answers

Answer 1

A solution with an 8% (m/m) concentration was created by dissolving the sodium chloride in 40.0 g in 500.0 g of water. Sodium chloride, also known as table salt.

Sea salt has the chemical formula NaCl, which indicates a 1:1 ratio of sodium chloride ions, and is an ionic material despite also containing other chemical salts. With molar weights of 22.99 and 35.45 g/mol, respectively, 39.34 g of Na and 60.66 g of Cl make up 100 g of NaCl. The concentration can apply to any type of chemical mixture, even though it is most frequently used to describe solutes and solvents in solutions. Two variations of the molar (amount) concentration are the normal concentration and the osmotic concentration.

(40.0/500)*100, which equals 8, is the concentration formula.
