C1=10%
Ms=250g
C2=60%
Ms2=40g
Cfinală=?
[tex]md1 = \frac{c1 \times ms1}{100} = \frac{10 \times 250}{100} = 25g[/tex]
[tex]md2 = \frac{c2 \times ms2}{100} = \frac{60 \times 40}{100} = 24g[/tex]
[tex]md \: finala = md1 + md2 = 25g + 24g= 49g[/tex]
[tex]ms \: finala = ms1 + ms2 = 250g + 40g = 290g[/tex]
[tex]c \: finala = \frac{md \: finala}{ms \: finala} \times 100 = \frac{49g}{290g} \times 100 = 0.1689 \times 100 = 16.89\%[/tex]
