✭ How many grams of ethylene glycol should be mixed with 375 mL of water to make a 7.50% (v/v) mixture?
\large\underline{\sf{\gray{Solution}}}
Solution
◈ Let volume of solute (ethylene glycol) be 'v' mL
━━━━━━━━
Finding volume of the solution,
\small\sf\Rightarrow\: Volume_{(solution)} = Volume_{(solute)} + Volume_{(solvent)}⇒Volume
(solution)
=Volume
(solute)
+Volume
(solvent)
\small\Rightarrow\:\sf Volume_{(solution)} = v + 375⇒Volume
(solution)
=v+375
\small\Rightarrow\:\sf \pink {Volume_{(solution)} = (v + 375)\:mL}⇒Volume
(solution)
=(v+375)mL
Now,
➳ \small\sf Concentration\:(v/v) = \dfrac{Volume_{(solute)}}{Volume_{(solution)}}\:\times\:100Concentration(v/v)=

➳ \small\sf 7.5 = \dfrac{100v}{v + 375}7.5=
v+375

➳ \small\sf 7.5(v + 375) = 100v7.5(v+375)=100v
➳ \small\sf 7.5v + 2812.5 = 100v7.5v+2812.5=100v
➳ \small\sf 2812.5 = 100v - 7.5v2812.5=100v−7.5v
➳ \small\sf 2812.5 = 92.5v2812.5=92.5v
➳ \small\sf v = \dfrac{2812.5}{92.5}v=
92.5
2812.5
➳ \small\sf v = {\cancel{\dfrac{2812.5}{92.5}}}v=
92.5
2812.5
➳ \small\sf\pink{ v = 30.4\:mL}v=30.4mL
We know that,
⪼ \underline{\boxed{\sf{Mass = Volume\:\times\:Density}}}
Mass=Volume×Density
Finding mass of ethylene solution to be mixed,
\small\sf \rightarrow\: Mass_{(ethylene\:glycol)} = Volume_{(ethylene\:glycol)} \:\times\: Density_{(ethylene\:glycol)}→Mass
(ethyleneglycol)
=Volume
(ethyleneglycol)
×Density
(ethyleneglycol)
\small\rightarrow\:\sf Mass_{(ethylene\:glycol)} = 30.4 \:\times\:1.09→Mass
(ethyleneglycol)
=30.4×1.09
\small\rightarrow\:\sf\pink{Mass_{(ethylene\:glycol)} = 33.136\:g}→Mass
(ethyleneglycol)
=33.136g
\small\therefore\:{\underline{\sf{Mass\:of\:ethylene\:glycol\:to\:be\:mixed\:=\:{\textsf{\textbf{33.136\:g}}}}}}∴
Massofethyleneglycoltobemixed=33.136g
