What mass of hydrogen is produced when 4.00 moles of zinc react completely in the following equation? Zn + 2HCl $\rarr$ZnCl₂ + H₂

Question

Quizplus · Accepted Answer

The balanced equation shows that 1 mole of Zn produces 1 mole of H2. Therefore, 4.00 moles of Zn will produce 4.00 moles of H2. The molar mass of H2 is approximately 2.02 g/mol, so 4.00 moles of H2 will have a mass of 4.00 x 2.02 g/mol = 8.08 g.
