1 gram of any sample contains 1 mole of molecules. No it is NOT , it's only true for protons!
Two or more atoms of same kind come together to form a molecule.
Mole is a unit that is used repeatedly in introductory chemistry classes.
Added:
- a molecule is a group of chemically bonded atoms.
- a mole is a number, like a dozen is 12, a mole is 6.022 x 10^23 , (6.022 x 1023).
Eg. 1.0 grams of H2 is equal to 0.5 mole H2 and it contains 3.011 x 1023 H2 molecules
and 1.0 grams of O2 is equal to 0.03125 mole O2, it contains 1.882 x 1022 O2 molecules

Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
Is an atom bigger than a mole?
An atom is a component of matter; mole is a unit for the amount of substance in SI. Of course a mole of atoms is bigger than a single atom.
What is a mole atom?
A mole, in terms of chemistry usually, represents a number. That number is about 6.022 x 10^23. So when you have a mole of something, you have 6.022 x 10^23 of something. Moles are used in chemisty because the mass of a mole of any molecule in grams is the same as the atomic mass of the molecule in amu's.
How many oxygen atoms are in 0.02 mol of silver phosphate?
There are 4 O atoms per molecule Ag3PO4 .In 0.02 mole Ag3PO4 are0.02(mole) * 6.022*10+23(molecules/mole) * 4(atolms/molecule) = 4.8*10+22 atoms Oxygen
The number of molecules in one mole?
if you have H2SO4. that is 1 mole of that molecule if you have 2H2SO4. that is 2 moles of that molecule.
Does carbon dioxide represent a mole or a molecule?
A molecule.
What is the root word for molecule?
the root word for molecule is mole
Why is a scientific mole called a mole?
The Oxford English Dictionary traces it back to the German word for molecule.
Can a mole represent a molecule?
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
What is the mass of 0.256 molecule of water?
0.256 molecule of anything does not exist. The smallest representation of any compound is 1 molecule. If you mean 0.256 mole then: 0.256 mole x (18 g / mole) = 4.608 grams
Can scratching a mole make it bigger?
Scratching a mole will not make it get bigger.I scratch my mole on my arm every day and it never got bigger.
How many grams of the molecule C12O16H1 would be equal to 1 mole of the molecule?
In every mole there are only 6.023X1023 molecules irrespective of the compound.
Why one mole of hydrogen molecule and one mole of hydrogen atoms have different masses?
because there are 2 hydrogen atoms in the molecule of hydrogen atoms
What is the difference between a molecule and a mole of carbon dioxide?
A molecule is the fundamental unit of a compound. Therefore, a molecule of carbon dioxide is one C and two O atoms bonded together. A molecule is a single unit whereas a mole is a group of molecules and represents a fixed no. of any substance. Therefore, one mole of Carbon Dioxide consists of a 6.022 x 1023 molecules
How does the experimental mole ratio compare with the theoretical mole ratio?
the experimental mole ratio has a bigger penis
Is insulin or glucose bigger?
An insulin molecule is much bigger than a glucose molecule.
Is mole the same as molecule?
A mole is defined as the amount of substances which contains Avagadro number of particles. A molecule is defined as the number of atoms contaned in it > For example , Oxgen molecule contains 2 atoms.
