It refers to a solution each litre of which contains one tenth of a mole of a particular substance. A mole is a specific number of atoms or molecules - 6.02 x 10 to the power of 23, also known as Avogadro's number. One mole of any substance has a mass equal to its atomic or molecular weight expressed in grams. Thus, one mole of Helium has a mass of 2g; one mole of Sodium Chloride - NaCl - has a mass of 22.98g + 35.45g = 58.43g. It follows that a 0.1 molar solution of NaCl contains 5.843g of NaCl in each litre of solution.

What is solubility of salt in moles per liter?
Approx. 6 mol/L at r.t.
Grams per liter into moles per liter how to convert?
To convert grams per liter to moles per liter, you need to know the molar mass of the substance in grams per mole. Divide the given mass in grams per liter by the molar mass to get moles per liter. This conversion allows you to express the concentration of a substance in terms of its molecular weight, facilitating comparisons and calculations in chemistry.
When determine the molarity of a solution you must make sure that your answer is in terms of?
moles of solute per liter of solution.
What is dimention of universal gas constant?
In SI units J K-1 mol-1 (Joules/ Kelvin mol or Joules per kelvin per mol) in some older chemistry text books they quote L atm K-1 mol-1 (liter atmospheres per degree kelvin per mol) (see wikipedia "Gas constant" for a list of the dimensions in other systems of units)
How is molarity expressed?
Molarity is typically expressed as the number of moles of solute per liter of solution. It is represented in units of moles per liter (mol/L) or sometimes as molarity (M).
