Jak oblicza się stosunek liczby atomów pierwiastków i stosunek masowy
a)mH₂=2*1u=2u
b)mF₂=2*19u=38u
c)mH₂O=2*1u+16u=2u+16u=18u
d)mCO₂=12u+2*16u=12u+32u=44u
e)mH₂S=2*1u+32u=34u
f)mSO₃=32u+3*16u=32u+48u=80u
g)mNH₃=14u+3*1u=14u+3u=17u
h)mC₂H₆=2*12u+6*1u=24u+6u=30u
i)mC₃H₈=3*12u+8*1u=36u+8u=44u
j)mH₂SO₃=2*1u+32u+3*16u=2u+32u+48u=82u
k)mC₂H₅OH=2*12u+5*1u+16u+1u=24u+5u+17u=46u
l)mCH₃COOH=12u+3*1u+12u+2*16u+1u=24u+3u+32u+1u=60u
ł)mC₂H₄(OH)₂=2*12u+4*1u+2*16u+2*1u=24+4u+32u+2u=62u
m)mC₃H₅(OH)₃=3*12u+5*1u+3*16u+3*1u=36u+5u+48u+3u=92u
np. dla Al2O3
mAl2O3=54u+48u=102u
stosunek liczby atomów
nAl : nO = 2 : 3
stosunek masowy
mAl : mO = 54 : 48
mAl : mO = 9 : 8
