Nu este citet !!!!!!
1.C=15%
md=60g sare
c= mdx100/ms---> ms= 100xmd/c= 100x60/15 g= 400g
dar ms= md+m,apa---> m,apa= ms-md= 400-60 g=> 340g
2.c=25%
ms= 2g
m,apa= 300g??????? Nu este clar ce se da , ce se cere ???????
c= mdx100/ms---> md= cxms/100= 25x2/100g= 0,5g
ms=md+m,apa--> mapa= ms-md= 2-0,5g= 1,5g
