Question

A 210 ml solution contains 30 ml of solute How much is its percent by volume?

Answer 1

★ Solution :-

• Mass of solution = 210 ml
• Mass of solute = 30 ml
• Mass of solvent = 210 - 30 = 180 ml

Mass of solution by volume %,

$\longrightarrow\:\: \sf{\dfrac{Mass \:of\:solute}{Volume \:of\: solution} \times 100}$

$\longrightarrow\:\: \sf{\dfrac{30}{210} \times 100}$

$\longrightarrow\:\: \sf{\dfrac{15}{105} \times 100}$

$\longrightarrow\:\: \sf{\dfrac{3}{21} \times 100}$

$\longrightarrow\:\: \sf{\dfrac{1}{7} \times 100}$

$\longrightarrow\:\: \sf{14.28\: ml}$

∴ Volume % = 14.28 ml
