What is the mass of one mole in urea?
Pure Urea (H2N-CO-NH2) has a mole wt of 60.06. SO ... 60.06 gm is one gm mole.
Why one molal solution of urea is dilute as compare to one molar solution of urea?
A one molal solution of urea contains one mole of urea dissolved in one kilogram of solvent (usually water), while a one molar solution contains one mole of urea dissolved in one liter of solution. Since the density of the solution can vary, a one molal solution typically has a lower concentration of urea in terms of volume compared to a one molar solution, making it more dilute. This is because the molarity takes into account the total volume of the solution, while molality focuses only on the mass of the solvent.
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.
What is the mass of one mole of an element that has an atomic mass of 6.94?
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
What has more mass one mole of helium or one mole of lead?
Lead. The molar mass of lead is 207.2 g/mol while helium's is 4.0 g/mol.

Which has a greater mass.. one mole of silver or one mole of gold?
One mole of gold has a greater mass than one mole of silver because gold has a higher atomic mass compared to silver. The atomic mass of gold is around 197 grams per mole, whereas the atomic mass of silver is around 108 grams per mole.
What is the mass of one mole?
It depends on the substance. A mole is just a unit of amount, 6.02 × 1023. So that means that one mole of atoms is 6.02 × 1023 atoms; likewise, one mole of cars is 6.02 × 1023 cars and one mole of rice is 6.02 × 1023 grains. A mole of cars has a different mass than a mole of rice, so until you define what you're measuring, this question cannot be answered.

What has a greater mass one mole of silver or one mole of gold?
Gold

What is the mass 1 mole of carbon?
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ratio of isotopes equal to that in nature - has a mass of 12.0107 grams.
What is the mass of one mole of sodium atom?
HI, A MOLE IS MOLECULAR MASS. MOLECULAR MASS OF SODIUM IS 23. HENCE, 1.22 MOLE = 1.22*23 = 28.60
What is the mass of one mole atom of sulfur?
32 grams, you can find the mass of one mole of any element by looking at its atomic mass eg chlorine has Atomic mass of 35.5 so the mass of one mole of chlorine is 35.5 grams.
