Question

ms1= 600g , c1%=60 , c2%=30 , calculati m apa

Answer 1

ms1=600g
c1=60%
c2=30%
$c1 = \frac{md}{ms1} \times 100$
$md = \frac{c1 \times ms1}{100} = \frac{60 \times 600}{100} = 360 \: g$
ms1=md+m apă1 =>
m apă1=ms1-md=600-360=240 g
$c2 = \frac{md}{ms2} \times 100$
$ms2 = \frac{md \times 100}{c2} = \frac{ 360\times 100}{30} = 1200 \: g$
m apă2=ms2-ms1=1200-600=600 g
m apă=m apă1+m apă2=240+600=840 g
