The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.
Approximately (rounded to two significant figures.)
Explanation:
The unit of concentration is the same as (moles per liter.) On the other hand, the volume of both the solution and the original solution here are in milliliters. Convert these two volumes to liters:
.
.
Calculate the number of moles of in that of solution:
.
reacts with at a one-to-one ratio:
.
Coefficient ratio:
.
In other words, one mole of would neutralize exactly one mole of . In this titration, of was required. Therefore, the same amount of should be present in the original solution:
.
Calculate the concentration of the original solution:
