Question

Consider the equation below. Zn + H2SO4 mc010-1.jpg ZnSO4 + H2 The mole ratio of zinc to zinc sulfate is

2 Answer

  • Zn=65 grams/mole
    20 grams/ (65 grams/mole)=0.31 moles of zinc
    The molar ratio of Zn and H2 is 1 to 1, so 0.31 moles of H2 are also produced. The ratio is the same for the sulfuricĀ acid. H2SO4=2*1+32+16*4=98 grams/mole
    (98 grams/mole)*0.31 moles=30.4 grams of H2SO4.
  • Answer: The mole ratio of zinc to zinc sulfate is 1:1.

    Explanation:

    [tex]Zn+ H_2SO_4\rightarrow ZnSO_4+H_2[/tex]

    According to reaction,1 mole of zinc reacts with 1 mole of sulfuric acid to give 1 mole zinc sulfate and 1 mole of hydrogen gas .

    So, the mole ratio of zinc to zinc sulfate is:

    [tex]\text{moles of}Zn:\text{moles of}ZnSO_4=1 mol:1 mol=1:1[/tex]

    Hence, the mole ratio of zinc to zinc sulfate is 1:1.
