Question 25 POST_UTME_KSU • 2021 • CHEMISTRY • objective

A metal (M) reacts with chlorine gas to form a white solid. The reaction is as follows: M + Cl2 → MCl2. If 2.5 g of M reacts with 1.5 g of Cl2, what is the percentage yield of MCl2?

Answer Options

Correct Answer A. \( % yield = \frac{mass of MCl_2 produced}{theoretical mass of MCl_2} \times 100% \)
B. \( % yield = \frac{mass of M used}{theoretical mass of MCl_2} \times 100% \)
C. \( % yield = \frac{mass of Cl_2 used}{theoretical mass of MCl_2} \times 100% \)
D. \( % yield = \frac{mass of MCl_2 produced}{mass of M used} \times 100% \)
Correct Answer
A
Correct Option:
\( % yield = \frac{mass of MCl_2 produced}{theoretical mass of MCl_2} \times 100% \)
