Only if you have pure water in you mind: 1 liter of pure water weighs 1 kilogram.


Molarity means number of moles in a solute volume. So molarity is 2moldm-3.


specific gravity is 1gm per cc that means 1000 gm per liter and molarity is gm per liter /molecular weidgt = 1000/18\ we have, gm/lt= Molarity*Mol mass so, 1000=molarity*18(for water H2O) thus, molarity= 1000/18


# of moles of solute Molarity = -------------------------- 1 Liter of solution



The density of liquid water is 1000 grams / liter. Since molarity is given by moles per liter, convert 1000 grams into moles. 1000 grams (1 mole/18.02 grams) = 55.49 moles So, 55.49 moles per liter = 55.49 M. Molarities for solid and gaseous water are different; densities are different, but same steps as I showed for solving.


1 liter of pure water weighs 1 kilogram or 1000 gram. 20 liter of pure water weighs 20 kilogram or 20,000 gram.


In metric, one liter = 1 kg. Therefore, 1 liter of distilled water should be 1 kg.


1 liter is 1 cubic decimeter or 1000 cubic centimeters. Only if it is pure water you can say: 1 liter of water weighs 1 kilogram.


1 liter of pure water under standard conditions has a mass of 1 kilogram.


Only if you think of pure water, you can say: 1 liter of water weighs 1 kilogram.


2 moles in 0.5 liters will mean 4 moles in 1 liter. So the molarity is 4 molar.


Molarity gives the no. of moles of solute per litre of the solutionFor instance, 1 M HCl means 1 mole of pure HCl in 1 L of water



Only if you have pure water in mind, then: 1 liter or 1000 milliliters of pure water weigh 1000 grams or 1 kilogram. 0.015 liter or 15 milliliters of pure water weigh 15 grams or 0.015 kilogram.


A liter of pure water weighs at most 1 kilogram (at 4 degrees Centigrade). This is about 2.2 pounds. Water at higher temperatures is less dense and will weigh slightly less.


I liter of H2O equals one kilogram, in fact one kilogram is actually the equal weight of 1 liter of pure water (H2O)


There would be 117g of NaCl in 1000 ml or 1 liter. The MWt of NaCl is 58.5 so 117/58.5 is 2.00 - so the molarity is 2.00 moles per liter of NaCl


1 cubic decimeter of pure water is 1 liter. It weighs 1 kilogram.


Molarity = moles of solute/Liters of solution 10 grams of compound ( 1mol/100g ) = 0.1 mole Molarity = 0.1 mol/1 Liter = 0.1


NaF has an atomic mass of 42, therefore if you dissolve 42 grams (1 mole) of it in 2 liters of water you get a molarity of 0.5 moles/Liter.


The density of water is 1g/ml, so if you do dimensional analysis, you can find that in 1 L of water, there is 55.56 mol, which means the molarity of water is 55.56.


The concentration of pure water is 55 molar. In other words, 1 liter of water holds 55 moles of H2O


Molarity or molar concentration is a unit of concentration, symbolized by "M". It is the ratio of the number of moles of solute and the volume of solution (in liters).Molarity = Moles of solute ÷ Liters of solution = moles/liter = Mmolarity is define as the number of mole of a solute in 1 liter of solution.


1 liter of pure water at standard temperature and pressure has 1 kilogram of mass. Accordingly and consequently, 1/2 liter would have 1/2 kilogram of mass under the same conditions.
