1) Oblicz ile gramów waży 6M CuO ?
2) Oblicz masę cząsteczkową a) CO b) CO2 c) Al2O3 d)NaOH e)Al(OH)3 f) H2SO4
1. nie wiem
2. a) 12u + 16u = 28u
b) 12u + 2*16u = 12u + 32u = 44u
c) 2*27u + 3*16u = 54u + 48u = 102u
d) 23u + 16u + 1u = 40u
e) 27u + 2*(16u + 1u) = 27u + 2*17u = 27u + 34u = 61u
f) 2*1u + 32u + 4*16u = 2u + 32u + 64u = 98u
