potrzebuje tego zadania na dziś to jest coś z układu okresowego pierwiastków chemicznych
m h2 so4=
m ca 0
m naf
m H = 1u
m S= 32u
m O= 16u
m Ca = 40u
m Na = 23u
m F = 19u
m H₂SO₄ = m 2 H + m S + m 4 O = 2*1u + 32u + 4*16u = 98u
m CaO = m Ca + m O = 40u + 16u = 56u
m NaF = m Na + m F = 23u + 19u = 42u
1.
m S = 32u
m O = 16u
2.
3.
