Question

A solution contains 40 g of common salt in 320 g of water. calculate the concentration in the terms of mass by mass percentage of the solution.​

Answer 1

Explanation:

The muscles which move without our volition are called involuntary muscles. For example, the cardiac muscle in the heart and the smooth muscles are involuntary muscle.

Answer 2

Answer:

→ Hey Mate,

→ Given Question : A solution contains 40 g of common salt in 320 g of water. calculate the concentration in the terms of mass by mass percentage of the solution.​

→ Solution : Mass of solute ( salt )  = 40 g

→                : Mass of solvent ( water ) = 320 g

→ we know,  

→   Mass of solution = Mass of solute + Mass of solvent

→                               = 40 g + 320g

→                               =  360g

→ Mass percentage of solution :

→ $\frac{Mass of solute}{Mass of solvent } X 100$

→ $\frac{40}{360} X 100 = 11.1$  percent.

Explanation:

thank you
