1. Given: UreaMolar Mass = 60.06g
Required: Number of Hydrogen atoms in 25.6g of (NH2)2CO
Formula:
Solution: n = 1 mole 6.022x1023 molecules 4 H atoms
25.6 g x ---------- x -------------------------------- x --------------
60.06g 1 mole 1 molecule
n = 1.03 x 1024 H
Answer: There are 1.03 x 1024 H atoms in 25.6g of (NH2)2CO
What else can I help you with?
Is urea crystals element?
No, urea crystals are not an element. Urea is a compound composed of carbon, nitrogen, oxygen, and hydrogen atoms.
Can ethanol glycerol sucrose urea and 1-decanol hydrogen bond with water?
Yes they can. The hydroxyl groups in ethanol, glycerol, sucrose, and urea will form hydrogen bonds with water. In 1-decanol the long non-polar chain of carbon and hydrogen atoms tends to render the compound immiscible with water, but the -OH group could still theoretically form a hydrogen bond.
What compound is made up of four elements?
The compound urea is made up of four elements-nitrogen , hydrogen, carbon and oxygen. The formula for urea is NH2CONH2 .
Which has higher boiling point Urea or Sodium chloride?
Sodium chloride (NaCl) has a higher boiling point than urea. This is because sodium chloride forms ionic bonds which are stronger than the hydrogen bonds in urea. Stronger bonds require more energy to break, resulting in a higher boiling point.
Is urea an organic compound or inorganic?
Urea is an organic compound because it contains carbon atoms covalently bonded with other elements like nitrogen and oxygen. It is produced in living organisms as a waste product of protein metabolism.
Is urea crystals element?
No, urea crystals are not an element. Urea is a compound composed of carbon, nitrogen, oxygen, and hydrogen atoms.
How many atoms are in urea?
The number of atoms in urea will depend on the number of urea molecules present. In one MOLECULE of urea there are 8 atoms. There are 2 N atoms, 4 H atoms, 1 C atom and 1 O atom. The structural formula of urea is H2NC(O)NH2
How to calculate no. of atoms of hydrogen carbon oxygen nitrogen present in 5.6gram of urea?
Find the molar mass of urea (CH4N2O) by adding the atomic masses of carbon, hydrogen, oxygen, and nitrogen. Then, divide the given mass of urea (5.6g) by the molar mass to find the number of moles. Finally, use the subscripts in the chemical formula to determine the number of atoms of each element in one mole of urea.
Is urea aliphatic or aromatic?
Urea is considered aliphatic because it is composed of carbon, hydrogen, and nitrogen atoms arranged in a linear structure, rather than in a cyclic aromatic structure.
What kind of compound is urea?
Urea is an organic compound known as a carbamide, containing carbon, nitrogen, oxygen, and hydrogen atoms. It is a common nitrogen-containing waste product in animals, produced in the liver and excreted by the kidneys in urine. Urea is also widely used in agriculture as a fertilizer and in skincare products for its moisturizing properties.
What two substances does urea make up?
Urea is made up of carbon, nitrogen, oxygen, and hydrogen atoms. It is a compound formed from ammonia and carbon dioxide during the liver's breakdown of proteins.
What is the maximum theoretical number of water molecules that one urea molecule can hydrogen bond with?
The formula for urea can be written as (NH2)2CO. This formula shows that there are two atoms of nitrogen, four atoms of hydrogen, and one atom each of carbon and oxygen, for a total of eight atoms.
How urea is organic?
The formula of urea is CO(NH2)2. It is organic because the formula contains a carbon atom. The only compounds that contain carbon and are not considered organic are carbon dioxide and carbonates such as calcium carbonate.
Can ethanol glycerol sucrose urea and 1-decanol hydrogen bond with water?
Yes they can. The hydroxyl groups in ethanol, glycerol, sucrose, and urea will form hydrogen bonds with water. In 1-decanol the long non-polar chain of carbon and hydrogen atoms tends to render the compound immiscible with water, but the -OH group could still theoretically form a hydrogen bond.
What is urine element compound or mixture?
Ammonia is a compound. It consists of the elements nitrogen and hydrogen. In one ammonia molecule, there is one nitrogen atom and three hydrogen atoms. The chemical formula for ammonia is NH3.
Is urea soluble in ethanol?
Yes, urea is soluble in ethanol. Urea is a polar compound that forms hydrogen bonds with the polar solvent ethanol, which allows it to dissolve in ethanol.
Why urea is organic compound?
Urea is considered an organic compound because it is composed of carbon, hydrogen, and oxygen atoms arranged in a specific structure. It is produced by living organisms, specifically in the liver, as a way to eliminate excess nitrogen from the body. This compound is widely used in fertilizers and various industrial applications.
