Chemistry · Secondary 3 · Medium · The mole
In an experiment, 6.0 g of magnesium reacts completely with excess dilute hydrochloric acid to form magnesium chloride and hydrogen gas.
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
Relative atomic mass: Mg = 24.
How many moles of hydrogen gas are produced?
Mg(s) + 2HCl(aq) → MgCl₂(aq) + H₂(g)
