Answer:
The three components of air are all classified as pure substances since they are not chemically bonded so they can be separated by certain processes and be present as a pure substance.
Explanation:
Answer:
0.1814 M
Explanation:
From the balanced equation of reaction:
2 mole of the permanganate requires 5 moles of oxalic acid.
Mole of 0.3577 g of oxalic acid =
= 0.3577/90.03
=0.00397 mole
Mole of permangante that will require 0.00397 mole of oxalic acid:
= 5 x 0.00397/2
= 0.00993 mole
Molarity of permanganate = mole/volume
Volume of permanganate = 54.77 mL = 0.05477 L
Molarity = 0.00993/0.05477
= 0.1814 M
<em>The molarity of the permangante solution is 0.1814 M</em>
It is a natural source that renews itself
