Some Basic Concepts Of Chemistry Question 45
Question: Two glucose solutions are mixed. One has a volume of 480 mL and a concentration of 1.50 M and the second has a volume of 520 mL and concentration 1.20 M. The molarity of final solution is
Options:
A) 1.20M
B) 1.50M
C) 1.34M
D) 2.70 M
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ M _1V _1+M _2V _2=M _3V _3(V _3=V _1+V _2) $ $ 1.5\times 480+1.2\times 520=M _3\times 1000 $ $ M _3=1.34M $
