Question:
24 g carbon react with oxygen to produce 88 g carbon dioxide. Find the amount of oxygen used.
24 g carbon react with oxygen to produce 88 g carbon dioxide. Find the amount of oxygen used.
Show Hint
By conservation of mass, mass of oxygen used equals mass of product minus mass of carbon.

16 g
32 g
48 g
64 g
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Law of conservation of mass: total mass of reactants equals total mass of products.
Step 2: Equation
\(\text{C}+\text{O}_2\rightarrow\text{CO}_2\).
Step 3: Calculate
Mass of \(\text{O}_2=88-24=64\ \text{g}\).
Final Answer:
The mass of oxygen used is 64 g. \[ \boxed{\text{(D) }64\text{ g}} \]
