You need a 75 % alcohol solution. On hand, you have a 260 mL of a 30% alcohol mixture. You also have 95 % alcohol mixture . How
user100 [1]

30 \: percent \: alcohol \: in \: 260 \: ml \\ alcohol = 0.3 \times 26 0= 78 \: ml

c( \gamma ) =  \frac{78 +  0.95\gamma }{260 +  \gamma }  \times 100

c( \gamma ) = 75

\frac{78 +  0.95\gamma }{260 +  \gamma }   = 0.75

78 +  0.95\gamma  = 0.75 \gamma  + 195 \\ 0.2 \gamma  = 117 \\  \gamma  = 585

we \: need \: 585 \: ml \: of \: 95% \: alcohol
