100 ml aqueous solution `("density"(5)/(3)gm//ml)` contains `40%` by weight NaOH. The number of molecules of NaOH dissolved in the above solution is :
`("Use" N_(A)=6xx10^(23))`

An aqueous solution of NaOH having density 1.1. kg / dm^3 contains 0.02 mole fraction of NaOH. Number of molecules of NaOH present in its s10 mL solution is

The molarity of a solution containing 5.0g of NaOH in 250 mL solution is :

4gm of NaOH is dissolved in 250ml of a solution. calculate its molarity.

NaOH aqueous solution is labelled as 10% (w/v). Density of the solution is 1.02 g/ml. Then the mole fraction of the solute in the solution is

The molarity of a solution containing 5.0 g of NaOH in 200 mL solution is

Calculate the molarity of a solution containing 0.5 gm of NaOH dissolved in 500 ml. solution-

The density of a pure liquid (molecular mass =80) is 1.5 gm/ml. if 4 ml of liquid contains 60 drops then the number of molecules per drops of liquid is give by : [Given N_(A)=6xx10^(23) ]

10 g if NaOh us dissolved in 200 mL of solution. Calculate the strength.
