Question
$1 \text{ mole}$ of $BaCl_2$ is mixed with $1 \text{ mole}$ of $Na_2SO_4$. How many moles of $BaSO_4$ will be precipitated?
Answer: 1
💡 Solution & Explanation
$BaCl_2 + Na_2SO_4 \rightarrow BaSO_4 \downarrow + 2NaCl$. <br>Both reactants are in a $1:1$ stoichiometric ratio. $1 \text{ mole}$ of each gives exactly $1 \text{ mole}$ of precipitate.
