0,2=ms/200
ms=40g
Cp=(40+20)/(200+20+50) x 100%
Cp=22%
Cp₁= 20%
ms₁= ?
mr₁=200g
ms= Cp*mr
--------
100% to cp * mr ---- 100% to ----- jest kreska ulamkowa
ms₁=20%*200g
---------
100% procenty sie skrucą i 100 z 200 tez
ms₁=40g
roztwór drugi
Cp₂=?
ms₂= ms₁+20g=40g+20g=60g
mr₂=mr₁+50g+20g=200g+50g+20g=270g
Cp=ms *100%
----
mr
Cp₂=60g*100%
---------
270g gramy sioe skroca
Cp2≈22,22%
