Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
What is the mole concentration of 58.44g of NaCl in 1 L of water?
Molarity = moles of solute/Liters of solutionGet moles NaCl.58.44 grams NaCl (1 mole NaCl/58.44 grams)= 1 mole NaCl------------------Molarity = 1 mole NaCl/1 liter= 1 M NaCl========
Is 1 mole of Na Cl and 1 mole of MgCl2 has same No of ions?
A mole is simply a number of particles (atoms, molecules, cats...anything) and it is equal to 6.023x10^23. So yes, 1 mole of NaCl will have 6.023x10^23 ions, and MgCl2 will have the same number of ions. However, the proportions of each ion will differ in each case.
Why one mole of different compounds have different masses but have same number of molecules?
One mole of different compounds have different masses but have same number of molecules because that is the definition of a mole - a mole is about 6.022x1023 molecules of any particular material - and is normalized to the mass of Carbon-12.
Avogadro's number 6.02 x 10²³ refers to?
how many atoms, molecules and ions are present in one mole of a substance
What are the maximum number of formula units of NaCl in one mole?
6.022 x 1023
What is the number of molecules in 16.75 g of NaCl?
1 mole NaCl = 6,02×10237.5 x (6,022 ×1023 )
What is the number of ions in a 6.58 mole sample of NaCl?
The number of ions in a 6,58 mole sample of NaCl is 79,25137367812.10e23.
How many molecules of NaCl are in the 1 M NaCl solution?
It depends on how much solution you have!"1 molar solution" means that 1 litre of the solution contains 1 mole of solute (in this case, Na+ and Cl- ions). Therefore, 1 litre of 1M NaCl will contain 1 mole of sodium chloride. 1 mole is avagadro's number (6.02x1023) of a substance. If you have two litres of solution, obviously, you will have twice this number, for example.Note, though, that there are NO molecules of sodium chloride - sodium chloride is not a molecular substance.
Can a mole represent a molecule?
A mole represents a set number of molecules, not just 1 molecule. There are avagadro's number of molecules in a mole. Avagadro's number: 6.022x10^23
How do you calculate molecules to moles?
Multiply the number of molecules by the number of molecules per mole for that particular element or molecule (sum of the molecules/mole of each element in the molecule). The number of molecules per mole for any element can be found on charts and on the periodic table.
Does 1 mole of NaCl and 1 mole of MgCl2 have equal number of ions?

Which quantity is the same for one mole of ethanol and one mole of ethane?
The total number of molecules is equal.
How many atoms are needed to create 2 molecules in Na-CI?
1 mole has Avogadro's number of molecules, regardless of the formula for the molecule. 2 moles has 2 times Avogadro's number of molecules. Avogadro's number is approx 6.02 x 10e23 (that's 6.02 x 10 raised to the 23rd power). So multiply that by 2.
What is the equations for how many molecules are in 3 moles of NaCl?
Sodium chloride is an ionic crystalline salt, and does not form molecules. One unit of sodium chloride is called a functional unit. It is the lowest whole number ratio of ions represented in an ionic compound. 1 mole = 6.022 x 1023 formula units of NaCl 3 moles NaCl x 6.022 x 1023 formula units/mole = 1.8 x 1024 formula units of NaCl
Are molecules per mole a unit for avogadro's number?
No, the unit is "per mole". The number could be atoms or molecules but that is not part of the unit.
How many mole of NaCl are represented by 2.3 x 1012 molecules of NaCl?
The answeis is 3,82.1010 formula units (this expression is more corresct for ionic compounds).
