how many water molecules can bond to urea?
604729
Urea has an oxygen atom that can act as a hydrogen bond acceptor and with two lone-pairs of electrons, it can do this twice. The two NH2 N H 2 groups act as hydrogen bond donors and each hydrogen can form a hydrogen bond with water. So the total number of hydrogen bonds that urea can form with water is six.

For example, water and sugar are both molecules. Each molecule has a different size, so that determines how many would fit in a cubic inch of space. One cubic inch of water contains about 5x10^23 molecules. That means a five followed by 23 zeros.

Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.

Explanation: One molecule of H2O has 2 hydrogens then 5 molecules of water has 2 x 5 = 10 hydrogen atoms.

Therefore, 4 moles of water will have 4(6.022x10^23) number of water molecules.

Each water molecule can form two hydrogen bonds involving their hydrogen atoms plus two further hydrogen bonds utilizing the hydrogen atoms attached to neighboring water molecules.

Introduction. Water, with proteins and nucleic acids, is amongst the most important hydrogen-bonded substances. Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are attracted towards the oxygen atom of a neighboring water molecule; generally, a proton shared by two lone electron pairs.

Whereas water can form four hydrogen bonds (two H-acceptors and two H-donors), alcohols can only form three (two H-acceptors and one H-donor).

molecules in a drop of water = 1.67 x 1021 water molecules.

Then you want to multiply the molecules of urea by the number of atoms of the element in question that are present in Urea. So for example there are 2 atoms of N per molecule of Urea, therefore multiplying the molecules of urea you calculated earlier by 2 will yield the total number on nitrogen atoms present.

3.50⋅mol×6.022×1023⋅mol−1≅21×1023 individual water molecules.

The molecular formula of urea is CO(NH2)2 so there are 4 hydrogen atoms in every molecule of urea.

Calculating the number of particles Calculate the number of water molecules in 0.5 mol of water. It is important to be clear about the particles involved. For example, 3.011 × 10 23 water molecules contain 9.033 × 10 23 atoms.

An atom of oxygen and two atoms of hydrogen form water molecules by means of polar covalent bonds. Hydrogen bonds link hydrogen atoms already participating in polar covalent bonds to anions or electronegative regions of other polar molecules.
651076
In ammonia molecule( NH3 ), three hydrogen atoms form covalent bonds with nitrogen atom.

There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole. To calculate for 5 moles, (2 H atom)/(H2O molecule) X (6.022x10^23 H2O molecules)/(mole) X 5 moles = 6.022x10^24.

Each mole is 6.02214179 * 10^23 molecules. So we have 1.670829 *10^21 molecules. Each molecule of water has three atoms (two hydrogen, one oxygen). So we have 5.0124896 *10^21 atoms in one drop of water.
