Helo, reders welcome to “textilesgreen.in” today I m going to explain about h2o molar mass and more.
I have made this guide to help you out.
So, hold your seat and be with the end of guide.
So you could get valuable information out of it.
lets get started;
What is molar mass?
If you want to find the Molar mass of chemical compound, such as h2o then it is define as the mass of sample of that chemical compound divided by the amount of substance in that sample. this phenomenon is called molar mass.
It is measured in moles.
You know that the molar mass of element it can represent gram atomic mass and the molar mass of compound it can represent gram molecular mass.
• The relative atomic mass of an element expressed in gram is called gram atomic mass.
Gram atomic mass of oxygen is = O = 16g
• The relative atomic mass of an compound expressed in grams is called gram molecular mass.
O+O = 16+16 = 32 g
Where, O = oxygen
H+O+H = 1+16+1= 18g
Where, H = Hydrogen and O= oxygen
You can understand easily with the help of following structure.
1 unit of hydrogen = one atoms of hydrogen.
1 gram of hydrogen = one mole of hydrogen.
Value of 1 gram of hydrogen is = 6.022×10 rase power of 23.
About H2O (water)
18 units = one molecule of water
18 gram = one moles of water.
You know that units is much smaller then grams.
Find out molar mass of h2o.
find the molecular mass of h2o, it is find out with the help of following basic information.
First of all, You know that,
atomic mass of hydrogen = 1
atomic mass of oxygen = 16
Now, h2o molar mass is,
H = 1
Where, H= Hydrogen
In this chemical compound have two Hydrogen and one oxygen is present.
So, two Hydrogen = H2= 1+1 = 2.
Where, atomic mass of hydrogen= 1
But here, two Hydrogen is persent in h2o.
So, 1+1 = 2 or multiple by 2, in both cases, it will same meaning.
and one oxygen is persent so,
O= oxygen = 16
Where, atomic mass of oxygen is 16
So, for determine the molar mass of h20 add both atomic mass.
Now, atomic mass of h20 = 1+1+16 = 18 gram
So, molar mass of h2o is = 18 gram.
The molar mass of chemical compound is represente in gram molecular mass.
So, it is represente in gram for final result.
Molar mass of h2o is 18 gram.
