Question

300g roztworu zawiera 250g wody. Oblicz stezenie roztworu.

Answer 1

ms = 300g-250g = 50g

mr = 300g

 

Cp = 50g/300g*100% = 1/6*100% = 16i2/3% ≈ 16,7%

Answer 2

300-250=50
50/300*100%=5000/300=16⅔%
Powinno wyjść dobrze ;)

Answer 3

Ms=300g-250g=50g

300g-100%
50g-Cp

cp=50g*100%/300g=5000%/300=16,7%
