i don't want solution
just answer it fast
​

Answer 1

Given :

Volume of methyl alcohol = 40mL

Volume of petrol = 60mL

To Find :

Volume percentage of the solution.

Solution :

Name : Volume percentage

Symbol : % (v/V)

Definition : Volume of solute in mL dissolved in 100mL of the solution.

Effect of temperature : Changes with change in temperature

Formula :

$\underline{\boxed{\bf{\orange{\%\dfrac{v}{V}=\dfrac{Volume\:of\:solute}{Total\:volume\:of\:solution}\times 100}}}}$

• Volume of solute = 40mL
• Volume of solution = 100mL

$:\implies\sf\:\%\dfrac{v}{V}=\dfrac{40}{100}\times 100$

$:\implies\sf\:\%\dfrac{v}{V}=\dfrac{4000}{100}$

$:\implies\:\underline{\boxed{\bf{\purple{\%\dfrac{v}{V}=40\%}}}}$

■ Additional Information :

• Mass percentage : Amount of solute in grams in 100g of solution.
• Mass by volume percentage : Amount of solute in grams dissolved in 100mL of the solution.
• Parts per million : Number of parts of solute present in million (10⁶) parts of solution.
