“CONVETIR DE MOLES A GRAMOS”

35 gr de C₅H₅N

PM= 5(12) + 5(1) + 1(14)= 79g/mol 

N= 35g – 19mol = 0.44mol

28g de N₂0=

PM= 2(14) + 1(16) + 44g/mol  

N= 28g – 44mol = 0.63mol

25g de Ca₃(PO₃)₃

PM= 3(40) + 9 (30) + 9(16)=534 mol

N= 45g – 534 =0.17

18mol de H₂SO₄=

PM= 2(1) + (14) + 4(16)= 98g/mol

14mol de c₂H₃O₂Na=

PM= 2(12) + 3(1) + 2(16) + 1(23)= 86

N= 14mol – 86g= 1204
