Question

if 5 gram of dugar dissolve in 100cm cube of water is called​

Answer 1

Answer:

Answer:

\displaystyle \text{$Concentration \ \%=4.76 \ \%$}Concentration %=4.76 %

Explanation:

Given :

Mass of solute ( sugar ) = 5 g

Mass of solvent ( water ) = 100 g

Mass of solution = mass of solute + mass of solvent

Mass of solution = 5 g + 100 g = 105 g.

We know that concentration formula

\displaystyle \text{$concentration=\dfrac{mass \ of \ solute}{mass \ of \ solution}\times100 $}concentration=

mass of solution

mass of solute

×100

Now put the value here we get

\begin{gathered}\displaystyle \text{$Concentration \ \%=\dfrac{5g}{105g}\times100 $}\\\\\displaystyle \text{$Concentration \ \%=\dfrac{500\cancel g}{105 \cancel g}$}\\\\\displaystyle \text{$Concentration \ \%=\dfrac{500}{105} \ \%$}\\\\\displaystyle \text{$Concentration \ \%=4.76 \ \%$}\end{gathered}

Concentration %=

105g

Concentration %=

Concentration %=4.76 %

Thus we get answer.

Answer 2

Answer

Given :

Mass of solute ( sugar ) = 5 g

Mass of solvent ( water ) = 100 g

Mass of solution = mass of solute + mass of solvent

Mass of solution = 5 g + 100 g = 105 g.

We know that concentration formula

concentration=

mass of solution

mass of solute

×100

Now put the value here we get

Concentration %=

105g

5g

Concentration %=

105
