Calculati masele moleculare pentu 10 formule chimice dau bcoroana

Answer 1

M (NaCl) = 23 + 35.5 = 58.5 g/mol
M ( K2SO4 ) = 2×39 + 32 + 4×16 = 174 g/mol
M ( CO2 ) = 12 + 2×16 = 44 g/mol
M ( AgNO3 ) = 108+14+3×16 = 170 g/mol
M ( NaBr ) = 23 + 80 = 103 g/mol
M ( CuSO4 ) = 64 + 32 + 16×4 = 160 g/mol
M ( CaCl2 ) = 40 + 35.5×2 = 111 g/mol
M ( Ag3PO4 ) = 3×108 + 31 + 4×16 = 419 g/mol
M ( MgCO3 ) = 24 + 12 + 3×16 = 84 g/mol
M ( ZnS ) = 65 + 32 = 97 g/mol
