500ml દ્રાંવણમાં 10ml ગુલાબજળ દ્રવ્ય થાય તૌ તેની %v/v =_____

Answer»

$\blue{\underline{ \huge{ \blue{\boxed{ \mathfrak{\fcolorbox{red}{orange}{\purple{જવાબ \: :-}}}}}}}}$

દ્રાવણ નુ કદ = 500 ML

દ્રાવ્ય નુ કદ = 10 ml

%V/V = દ્રાવ્ય નુ કદ / દ્રાવણ નુ કદ × 100

%V/V = 10/500 × 100 =10/5 = 2%

${\star} \: \boxed{ \red{ \rm{\% \frac{v}{v} = 2\%}}}$
