Quick Answer: What is the mass in gram of 2 mole of water?

One mole of water has a molecular mass of 18 grams. Two moles of water have a molecular mass of 18×2=36 grams. Thus the molecular mass of two moles of water is 36 grams.

What is the mass of 2 mole of water?

One mole of H2 O 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. Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

What is the mass in grams of 2 moles?

According to the periodic table, 1 mol of U has a mass of 238.0 g, so the mass of 2 mol is twice that, or 476.0 g.

How many moles are present in 2 grams of water?

›› More information from the unit converter

The answer is 18.01528. We assume you are converting between grams H2O and mole.

What is the mass in grams of 1 mole of water?

The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of one mole of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol. Notice that the molar mass and the formula mass are numerically the same.

What is the mass of h2o?

One mole of water has a mass of 18 grams and volume of 18 milliliters or 0.018 liters. … A mole of water is Avogadro’s number of water molecules. Avogadro’s number is so large that it can be difficult to imagine its size.

What is the mass of 2.5 mole of water molecule?

Explanation: The number of molecules from moles by using Avogadro’s constant, 6.023×10²³ molecules/mol. =1.5×10²⁴ molecules is the mass of 2.5 moles of water.

How many molecules of water are in 2.5 moles of water H2O )?

Stefan V. 1.5×1024 molecules.

How do you find moles of water?

Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

What is the mass of 5 moles of H2O?

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.

How do you find the number of moles of water?

So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.
