1. HCOOH- kwas metanowy (mrówkowy)
m.cz. HCOOH- 2*1u + 12u + 2*16u= 46u
46u ----- 100%
32u ----- x
_____________
x= 32u * 100%/ 46u
x= 69,5 % O
12u ----- x
x= 12u * 100%/ 46u
x= 26% C
100% - 69,5% - 26% = 4,5 H
Najwiekszą zawartość procentową w HCOOH ma tlen 69,5%
2. mr= 920g, Cp= 20%
Cp= ms*100%/ mr |*mr
Cp * mr= ms * 100% |: 100%
ms= Cp*mr/ 100%
ms= 20% * 920g/ 100%
ms= 184g HCOOH
