Question

calcule as massas moleculares das substâncias indicadas:​

Answer 1

CO2= 16×2=32 12×1=1 2 32+12=44u

CaCO3= 40×1=40 12×1=12 16×3=48 40+48+12=100u

Cu2S= 63,5×2=127 32×1=32 127+32=159u

SO2= 32×1=32 16×2=32 32+32=64u

C2H6O= 12×2=24 6×1=6 16×1=16 24+6+16=46u

Fe2O3= 56×2=112 16×3=48 112+48=160u
