The solution would be like this for this specific problem:
Zn + 2HCl --> ZnCl2 + H2
Molar Mass Zinc - 65.38 g/mol
Molar Mass Zinc Chloride - 136.38 g/mol
Number of moles of zinc reacting = 0.600 g / 65.38g/mol = 0.00918 moles 0.00918 moles * 136.38 g/mole = 1.25 g ZnCl2
Answer = 1.25 grams of zinc chloride
I hope this helps and if you have any further questions, please don’t hesitate to ask again.
