"Molar mass of nickel acetate tetrahydrate"

The molar mass of nickel acetate tetrahydrate must first be detailed in its composition. The chemical formula of nickel acetate tetrahydrate may be $Ni (CH_ {3} COO) _ {2}\ cdot4H_ {2} O $.

To determine its molar mass, it is necessary to know the relative atomic mass of each element. The relative atomic mass of nickel ($Ni $) is about 58.69, carbon ($C $) is about 12.01, hydrogen ($H $) is about 1.01, and oxygen ($O $) is about 16.00.

In $Ni (CH_ {3} COO) _ {2}\ cdot4H_ {2} O $, there is 1 nickel atom, and its contribution mass is $58.69g/mol $.

Carbon atoms in acetate contain 2 carbons per acetate and 2 acetates, so the total number of carbon atoms is 2 dollars\ times2 = 4 $, and the total mass of carbon is 4 dollars\ times12.01g/mol = 48.04g/mol $.

Hydrogen atoms, acetate contains 3 hydrogen per acetate, 2 acetates contain 2 dollars\ times3 = 6 $hydrogen, 4 water molecules in tetrahydrate contain 4 dollars\ times2 = 8 $hydrogen, the total number of hydrogen atoms is 6 dollars + 8 = 14 $, and the total mass of hydrogen is 14 dollars\ times1.01g/mol = 14.14g/mol $.

Oxygen atoms, acetate contains 2 oxygen per acetate, 2 acetates contain 2 dollars\ times2 = 4 $oxygen, 4 water molecules contain 4 dollars\ times1 = 4 $oxygen, the total number of oxygen atoms is 4 dollars + 4 = 8 $, and the total mass of oxygen is 8 dollars\ times16.00g/mol = 128g/mol $.

The molar mass of nickel acetate tetrahydrate is: $58.69g/mol + 48.04g/mol + 14.14g/mol + 128g/mol = 248.87g/mol $.

From this, it can be seen that the molar mass of nickel acetate tetrahydrate is about $248.87g/mol $, which is important in various chemical calculations, such as the conversion of the amount, mass and molar number of the substance.
