Question

For the reaction $2P+Q\to R$, 8 mol of $P$ and 5 mol of $Q$ will produce:

• A. 8 mol of $R$
• B. 5 mol of $R$
• C. 4 mol of $R$
• D. 13 mol of $R$

Answer 1

Answer: (C)

4 mol of $R$

For the reaction $2P+Q\to R$

2 moles of $P$ combine with 1 mole of $Q$ will produce 1 mole of $R$

8 mol of $P$ and 5 mol of $Q$ will produce 4 mol of $R$.
