Will mark empirical formula for a compound is the radio of the atoms or moles of the elements in a compound

Empirical formula is the lowest whole number ratio of the atoms or moles of the elements in a compound.

Explanation:

Empirical formula:

It is the simplest formula gives lowest whole number ratio of the atoms or moles of the elements in a compound.

For example:

The empirical formula of glucose ( C₆H₁₂O₆) is CH₂O.

The empirical formula of benzene (C₆H₆)  is CH.

Consider  the following example:

The mass of sodium in a compound is 29 g, sulfur is 40.5 g and oxygen is 30.5 g. The empirical formula will be:

Solution:

Number of gram atoms of Na = 29.0/23 =1.261

Number of gram atoms of S = 40.5 / 32 = 1.266

Number of gram atoms of O = 30.5 / 16 = 1.906

Atomic ratio:

Na               :            S                  :    O

1.261/1.261 :       1.266/1.261     :   1.906/1.261

     1          :            1                    :         1.5

Na : S : O = 2  ( 1: 1 : 1.5)

Na : S : O = 2 : 2 : 3

Empirical formula is  Na₂S₂O₃.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

answer: the primary difference between a hypothesis and a theory is that b hypothesis is falsifiable, but a theory has been proven to be correct. theory is an explanation of something that is happening but hypothesis is a guess of something that can happen
