concentration of the resulting solution?

Sagot :

[tex]Concentration\ rate=\frac{mass\ of\ product}{mass\ of\ substance}*100\%\\\\ 15\%=\frac{m_1}{ms_1}*100\%\\ms_1=10pints\\ 15\%=\frac{m_1}{10}*100\%\\ \frac{15}{100}=\frac{m_1}{10}\ \ |*10\\ m_1=\frac{150}{100}=1,5pints\\\\ 10\%=\frac{m_2}{15}*100\%\\ 0,1=\frac{m_2}{15}\ \ |*15\\ 1,5=m_2\\ Resulting\ solution:\\ ms=ms_1+ms_2=15+10=25pints\\m=m_1+m_2=1,5+1,5=3pints \\\frac{m}{ms}*100\%=\frac{3}{25}*100\%=12\%[/tex]
