Question

calculate the concentration of mass per mass percentage if 50g of sugar is dissolved in 150g of water

Answer 1

Given :

Mass of solute = 50g

Mass of solvent = 150g

To Find :

We have to find percentage mass by mass concentration of solution$.$

SoluTion :

Name : Mass percentage

Symbol : %(w/W)

Definition : Amount of solute in grams present in 100g of solution.

Effect of temperature : No effect

Formula :

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

$\dashrightarrow\rm\:\%\dfrac{w}{W}=\dfrac{50}{50+100}\times 100$

$\dashrightarrow\rm\:\%\dfrac{w}{W}=\dfrac{5000}{150}$

$\dashrightarrow\underline{\boxed{\bf{\purple{\%\dfrac{w}{W}=33.33\%}}}}\:\orange{\bigstar}$
