Some Basic Concepts Of Chemistry Question 2
Question: The percentage of Se in peroxidase anhydrous enzyme is 0.5% by weight (atomic weight = 78.4). Then minimum molecular weight of peroxidase anhydrous enzyme is
Options:
A) $ 15.68 $
B) $ 1.568\times 10^{3} $
C) $ 1.568\times 10^{4} $
D) $ 3.136\times 10^{4} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ 0.5,g,Se\to 100,g $ peroxidase anhydrous enzyme $ 78.4,g,Se\to \frac{100\times 78.4}{0.5}=1.568\times 10^{4} $ Minimum molecular weight $ \to $ molecule at least contain one selenium.
