2g of NaOH is present in 200mL of solution. Weight percent of NaOH is

If 0.4gm of NaOH is present in 60 ml of solution. What is the molarity and normality [M. wt . Of NaOH = 40]

At 27^(@)C ,3.92 gm H_(2)SO_(4) is present in 250 ml solution. The osmotic pressure of this solution is 1.5 atm. If the osmotic pressure of solution of NaOH is 2 atm at same temperature, then concentration of NaOH solution is

The teacher instructed three students 'A', 'B' and 'C' respectively to prepare a 50% (mass by volume) solution of sodium hydroxide (NaOH). 'A' dissolved 50g of NaoH in 100 mL of water. 'B' dissolved 50g of NaOH in 100g of water while 'C' dissolved 50g of NaOH in water to make 100 mL of solution. Which one of them has made the desired solution and why?

4 g of NaOH are present in 0.1 dm^(3) solution have (a) mole fraction of NaOH , (b) molality of NaOH solution, (c ) molarity of NaOH solution, (d) normality of NaOH solution.

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

A given solution of NaOH contains 200 g of NaOH per litre of solution. Calculate the molarity, of this solution.

8g of NaOH is dissolved in 18g of H_(2)O . Mole fraction of NaOH in solution and molality (in mol kg^(-1) ) of the solutions respectively are:

8g of NaOH is dissolved in 18g of H_(2)O . Mole fraction of NaOH in solution and molality (in mol kg^(-1) ) of the solutions respectively are:

A solution is prepared by dissolving 1.0g of NaOH in water to get 250 ml of solution. Calculato its molarity.

A given solution of NaOH contains 2.00 g of NaOH per litre of solution. Calculate the molarity of this solution.
