Question

If there is 300gram solvent and 29gram solute .what is it's mass mass by mass percentage

Answer 1

Solution :

Given :-

▪ Mass of solute = 29g

▪ Mass of solvent = 300g

To Find :-

▪ %W/W of solution

Concept :-

▪ Mass percent of solution is given by ratio of mass of solute to the mass of solution.

Mathematically,

$\underline{\boxed{\bf{\pink{\%\dfrac{W}{W}=\dfrac{Mass\:of\:solute}{Mass\:of\:solution}\times 100}}}}$

Calculation :-

$\mapsto\sf\:\%\dfrac{W}{W}=\dfrac{29}{29+300}\times 100\\ \\ \mapsto\sf\:\%\dfrac{W}{W}=\dfrac{2900}{329}\\ \\ \mapsto\underline{\boxed{\bf{\purple{\%\dfrac{W}{W}=8.81\:\%}}}}$

Additional Information :-

• %W/W is not affected by temperature.
• %W/W shows mass percent of solute in solution.
• %V/V shows volume percenr of solute in solution.

Answer 2

Answer:

The mass by mass % is 8.81 %.

Explanation:

Mass of solute = 29 gram

Mass of solvent = 300 gram

A solution is a mixture of solute and solvent.

So, mass of solution =mass of solute +mass of solvent.

And, formula for mass by mass percentage is$\frac{mass \: of \: solute}{mass \: of \: solution} \times 100\%$

$= > \frac{29}{(29 + 300)} \times 100 \%$

$= > 8.81\%$
