Question

$\small\bold\pink{{Help\:Help\:help}}$​

Answer 1

Solution:

For solving this question, we use this formula:

$\maltese \: \: \boxed{ \sf{ \% \: by \: volume = \dfrac{volume \: of \: solute}{volume \: of \: solution} \times 100 }}$

Applying the above formula,

Column 1:

$\sf{ \% \: by \: volume = \dfrac{35}{60} \times 100 }$

$\implies \sf{ \% \: by \: volume = 58.33 \%}$

Column 2:

$\sf{ \% \: by \: volume = \dfrac{80}{40} \times 100 }$

$\implies \: \sf{ \% \: by \: volume = 200 \% }$

Column 3:

$\sf{ \% \: by \: volume = \dfrac{90}{30} \times 100 }$

$\implies \: \sf{ \% \: by \: volume = 300 \%}$

Column 4:

$\sf{ \% \: by \: volume = \dfrac{25}{50} \times 100 }$

$\implies \sf{ \% \: by \: volume = 50 \% }$

Therefore the answers for all the blanks in table are respectively:

1. 58.33 %
2. 200 %
3. 300 %
4. 50 %

Answer 2

Answer:

Solution :

Percentage of volume =

$\frac{volume \: of \: solute}{volume \: of \: solution} \times 100$

Columb 1:

Percentage of volume =35/60x100

= 58.33%

Columb 2:

Percentage of volume = 80/40x100

= 200%

Columb 3:

Percentage of volume = 90/30x100

= 300%

Columb 4:

Percentage of volume = 25/50x100

= 50%
