Question

a solution contain 60g of water sugar is 480g of water. calculate the concertraction of solutions in term of mas by mas ​

Answer 1

MASS BY MASS CONCENTRATION

We are given mass of solute(sugar) which is 60 g and solvent (water) which is 480 g

But, To find the concentration mass by mass, We need the mass of solute and mass of solution.

Further,

⇒ Mass of Solution = Mass of Solute + Mass of Solvent

⇒ Mass of solution = 60 + 480

⇒ Mass of solution = 540 g

Now, We can find the concentration (mass by mass),

⇒ m/m = Mass of Solute / Mass of Solution × 100

⇒ m/m = 60 / 540 × 100

⇒ m/m = 6/54 × 100

⇒ m/m = 1/9 × 100

⇒ m/m = 11.11 %

Hence, The mass by mass concentration of the solution is 11.11%

Some Information :-

◉ To Find the concentration in ppb (Parts Per Billion)

⇒ Concentration = Mass of Solute / Mass of solution × 10⁻⁹

◉ To find the concentration in ppm (Parts Per Million)

⇒ Concentration = Mass of Solute / Mass of Solution × 10⁻⁶

◉ To find the concentration in m/v (Mass by Volume)

⇒ Concentration = Mass of Solute / Volume of Solution × 100
