How much of NaOH is required to neutralise 1500 cm³ of 0.1 N  HCl  (At. wt. of  Na =23)

If 5.85 g  of NaCl (molecular weight 58.5) is dissolved in water and the solution is made up to 0.5 litre, the molarity of the solution will be

A mixture has 18g water and 414g ethanol. The mole fraction of water in mixture is (assume ideal behaviour of the mixture)

The number of molecules in 4.25 g of ammonia is approximately

The largest number of molecules is in

If 1 M and 2.5 litre NaOH solution is mixed with another 0.5 M and 3 litre NaOH solution, then molarity of the resultant solution will be

When a solute is present in trace quantities the following expression is used

When the concentration is expressed as the number of moles of a solute per litre of solution it known as

The normality of 2.3 M H₂SO₄ solution is

The molarity of a solution made by mixing 50ml of conc. H₂SO₄ (36N) with 50 ml of water is
