Answer 1

a) Dane:

mr1=400 g

Cp1=25%

mr2=400 g+50 g=450 g

Szukane:

ms=?

ms=Cp1*mr1/100%

Cp2=?

Cp2=ms*100%/mr2

Obliczenia:

ms=25%*400g/100%

ms=100 g

Cp2=100g*100%/450 g

Cp2=22,22%

b) Dane:

mr1=400 g

Cp1=25%

mr2=400 g+120 g=520 g

Szukane:

ms=?

ms=Cp1*mr1/100%

Cp2=?

Cp2=ms*100%/mr2

Obliczenia:

ms=25%*400g/100%

ms=100 g

Cp2=100g*100%/520 g

Cp2=19,23%

c) Dane:

mr1=400 g

Cp1=25%

mr2=400 g+20 g=420 g

Szukane:

ms1=?

ms1=Cp1*mr1/100%

ms2=?

ms2=ms1+20 g

Cp2=?

Cp2=ms2*100%/mr2

Obliczenia:

ms1=25%*400g/100%

ms1=100 g

ms2=100 g+20 g

ms2=120g

Cp2=120g*100%/420 g

Cp2=28,57%
