Oblicz masę kwasu solnego konieczną do uzyskania 4 moli chlorku cynku w reakcji kwasu z metalem
2HCl + Zn ⇒ ZnCl₂ + H₂
2 mole HCl - 1 mol ZnCl₂
8 moli HCl - 4 mole ZnCl₂
MHCl = 36,5g
8moli HCl = 36,5 × 8 = 292g
mHCl=36,5u
Zn + 2HCl---->ZnCl2 + H2
73g HCl------1mol ZnCl2
xg HCl--------4mole ZnCl2
x = 292g HCl
