Avogadro's number (L) tells you how many particles are in a mole L=6.022045 x 1023 (yes, it's a really really big number) So in two moles there are double that number of particles. Now, be clear in your mind about what you are asking: Avogadro tells you about particles, he doesn't care how many bits make up that particle. In one mole of hydrogen molecules you have two moles of hydrogen atoms. A mole of elephants will wear four moles of socks. A mole of moles will have four moles of little furry feet and two moles of blind moley eyes.

∙ 11y agoThe number of molecules in a mole of any element is a costant, Avogadro's constant. Avodadro's constant = 6.02214129×1023. 2 moles of any element will always contain twice Avogadro's constant or 1.204 428 258×1024 molecules.

∙ 14y agoAvogadro's constant: 6.02214179 × 1023 molecules
One mole of anything is Avogadro's constant.
which means that anything equals to 6.022 x 1023

∙ 11y agowell, i think there would be 2 hydrogen atoms and 1 oxygen atom for every molecule of H2O, so...do the math

How many hydrogen atoms in 80 water molecules?
Water is; H2O so; 80 * 2 = 160 hydrogen atoms
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many grams of hydrogen are in one mole of water?
One mole of any substance contains 6.022x10 to the power of 23 molecules of that substance. A water molecule contains two hydrogen atoms so one molecule of water has 12.044x10 to 23 hydrogen atoms.
How many H-atoms are present in 5 molecules of propane?
Five molecules of propane have 40 hydrogen atoms.
How many hydrogen atoms are in 6 molecules of HOCH2Ch2OH?
12
How many molecules of hydrogen in water?
There are two atoms of hydrogen in a water molecule, but no hydrogen molecules.
How many hydrogen atoms in 80 water molecules?
Water is; H2O so; 80 * 2 = 160 hydrogen atoms
How many molecules are present in a molecule of hydrogen?
there are 2 atoms of hydrogen in water
How many hydrogen atoms are needed to form five water molecules?
Chemical formula for water is H2O. One water molecule has 2 hydrogen atoms. That means 10 hydrogen atoms are needed to form five water molecules.The ration between hydrogen and oxygen in a water molecule is 2:1. In five water molecules, there are five oxygen atoms. According the ratio, there are 10 hydrogen atoms.
How many oxygen atoms are in water molecules?
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
How many oxygen atoms are in molecules of water?
3 oxygen atoms in three molecules of water.- There are 3 total atoms in water, which is H2O. There are 2 hydrogen atoms (H), and 1 oxygen atom (O).
How many atoms are in five molecules of hydrogen?
ten as each hydrogen molecules contains two atoms.
How many oxygen atoms are in 6 molecules of water?
6 atoms of oxygen are present. Three O2 contains 6 O atoms.
A sample of water contains 3.6 moles of hydrogen atoms How many molecules of water are present in this sample?
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
How many molecules contains 0.5L of c2h6o and how many hydrogen atoms?
The answer is 51,568.10 ex.23 molecules and 309,408.10 ex. 23 hydrogen atoms.
How many atoms of hydrogen are there in the mole of H2O molecules?
