What is the correct way to prepare a 1 molar solution of kno3?

In order to form the one molar solution we have to dissolve the 101.1 g of KNO₃ into one litter of water.

Explanation:

The molar mass of KNO₃ is 101. 1 g/mol. which means that

one mole = 101.1 g

In order to form the one molar solution we have to dissolve the 101.1 g of KNO₃ into one litter of water.

1L× 101.1 g/mol × 1 mol/L = 101.1 g

If you want to make the 2 litters of one molar solution then you should simply multiply the 101.1 g with 2.

2 L × 101.1 g/mol × 1 mol/L = 202.2 g

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
