Question

A solution containing 80 gram of sugar or salt in 500 gram of water calculate the concentration in the term of the mass by mass percentage of the solution

Answer 1

Answer:

13.79

Explanation:

mass of sugar(m1)=80g

mass of water(m2)=500g

mass of solution (m3)=500+80=580g

percentage of concentration=m1*100/m3

=80*100/580g

=13.79g

Answer 2

Given :

▪ Mass of sugar = 80g

▪ Mass of water = 500g

To FinD :

▪ Concentration of solution in the terms of the mass by mass percentage.

ConcentratioN of solutioN :

✴ Name : Mass percentage

✴ Symbol : %(w/W)

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

✴ Effect of temperature : No effect

CalculatioN :

$\dashrightarrow\tt\:\%\dfrac{w}{W}=\dfrac{Mass\:of\:solute}{Total\:mass\:of\:solution}\times 100\\ \\ \dashrightarrow\tt\:\%\dfrac{w}{W}=\dfrac{80}{(80+500)}\times 100\\ \\ \dashrightarrow\tt\:\%\dfrac{w}{W}=\dfrac{8000}{580}\\ \\ \dashrightarrow\underline{\boxed{\bold{\tt{\pink{\%\dfrac{w}{W}=13.79\%}}}}}\:\orange{\bigstar}$
