Answer:
4. gives the relative number of atoms of each element per formula unit
Explanation:
An empirical formula -
It refers to the formula which determined the simplest whole - number ratio of all the atoms in a given species , is referred to as an empirical formula .
In simple terms ,
It is he smallest formula of the whole number which when multiplied by some whole number gives the actual structure of the compound .
Hence , from the given information of the question ,
The correct option for empirical formula is 4.
Acids and Bases
Compound Formula % by Weight
Acetic acid, glacial CH3COOH 99.5
Formic acid HCOOH 90
Hydrochloric acid HCl 36
Nitric acid HNO3 71
Answer:
"1 M" will be the right solution.
Explanation:
The given values are:
Number of moles,
= 2 moles
Volume of solution,
= 2000 mL
or,
= 2 L
Now,
The molarity of the solution will be:
= ![\frac{Moles}{Liters}](https://tex.z-dn.net/?f=%5Cfrac%7BMoles%7D%7BLiters%7D)
On substituting the values, we get
= ![\frac{2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D)
= ![1 \ M](https://tex.z-dn.net/?f=1%20%5C%20M)
