Question

what is mean 10℅ sodium cloride

Answer 1

 We can make 10 percent solution by volume or by mass. A 10% of NaCl solution by mass has ten grams of sodium chloride dissolved in 100 ml of solution.

Weigh 10g of sodium chloride. Pour it into a graduated cylinder or volumetric flask containing about 80ml of water. Once the sodium chloride has dissolved completely (swirl the flask gently if necessary), add water to bring the volume up to the final 100 ml.

A 10% of alcohol solution by volume has ten ml of alcohol dissolved in 100ml of solution.

Measure 10ml of sodium chloride. Pour it into volumetric flask containing about 90ml of water (swirl the flask gently if necessary).

Hope This Helps.
