Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.
How many atoms are in 2 moles of H2O?
Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
How many particles are in 2 moles?
Deriving and Applying the Equation N = n × N A
|n (amount of substance in moles)||×||N (number of particles)|
|1 mol||×||6.022 × 1023 particles|
|2 mol||×||1.204 × 1024 particles|
|10 mol||×||6.022 × 1024 particles|
|0.5 mol||×||3.011 × 1023 particles|
What is the mass of 2 mole of water?
If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.
What is the mass of 2 moles of H2O?
One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.
How many atoms are in a mole?
Avogadro’s Number and the Mole. The mole is represented by Avogadro’s number, which is 6.022×1023 atoms or molecules per mol.
What is the mole of H2O?
Molar mass H2O = (2×atomic mass H) + (1×atomic mass O) = (2×1.00794) + (1×15.9994) = 18.02 • 1 H2O molecule has a mass of 18.02 amu. 1 mole of H2O molecules has a mass of 18.02 grams.
How did Avogadro find the mole?
The term “Avogadro’s number” was first used by French physicist Jean Baptiste Perrin. … If you divide the charge on a mole of electrons by the charge on a single electron you obtain a value of Avogadro’s number of 6.02214154 x 1023 particles per mole.
What name is given to the number of particles in a mole?
What is Avogadro’s number? Avogadro’s number is the number of units in one mole of a substance, or 6.02214076 × 1023. This number is also called the Avogadro constant.
How much does 1 mole of gold weigh?
A gold atom has an (average) atomic weight of 197.0 amu. That means that a MOLE of gold atoms will have a mass of 197.0 g.
What is the mass of one mole of water?
What is the mass in gram of 2 mole of water?
Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

How many grams of water are in 2.5 moles?
According to reaction below, when one mol of oxygen reacts with two mol of hydrogen, two mol of water is produced. Thus, when 2.5 mol of oxygen reacted with hydrogen, 2 * 2.5 mol = 5 mol of water is produced. The molar mass of water is 18 g/mol. One mol of water weighs 18 g.
What is the mass of 5 moles of H2O?
5 mole of water =0. 5×18 =9gm. Was this answer helpful?

›› More information from the unit converter
You can view more details on each measurement unit: molecular weight of 10 H2O or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles 10 H2O, or 28.01528 grams. Note that rounding errors may occur, so always check the results.
What is the mass of 5.00 moles of water?
From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.
