What mass of Zn will be dissolved in 10 mL pH=2 HCl solution?

Zn + 2HCl--> ZnCl2 + H2

  • Chemistry -

    [H+] = 10^-2 = 0.01M
    10 ml = 0.010L
    (0.01mol/L)(0.010L) = 0.0001 mole of H+ or HCl
    moles of Zn = (0.0001 mol HCl)(1mol Zn/2mol.HCl)= 0.00005 moles Zn
    Convert moles of Zn to grams
