ASSIGNMENT (NOVEMBER 8, 2011)

SA NOTEBOOK LANG PO ILALAGAY ITO


ASSIGNMENT:

1. NaCl

2. CO₂

dahil mahirap ipaliwanag yan, ipapa kopya ko na lang yung gawa ko sa ngayon lang...

1.) NaCl :

1 atom of Na = 23g x 1 = 23g
1 atom of Cl = 35g x 1 = 35g
Molecular Mass = 23g + 35g = 58g

%Na = ^23g⁄_58gx100% = 40%
%Cl = ^35g⁄_58gx100% = 60%


2.) CO₂

1 atom of C = 12g x 1 = 12g
2 atoms of O = 16g x 2 = 32g
Molecular Mass = 12g + 32g = 44g

%C = ^12g⁄_44gx100% = 27%
%2O = ^32g⁄_44gx100% = 73%


"x" means multiply
