If `250 mL` of a solution contains `24.5 g H_(2)SO_(4)` the molarity and normality respectively are:

A

`1M, 2N`

B

`1M, 0.5M`

C

`0.5 M, 1N`

D

`2M, 1N`

Text Solution

Verified by Experts

The correct Answer is:
A
`N=(24.5xx1000)/(98//2xx250)=2,M=(24.5xx1000)/(98xx250)=1`

If 100 ml of a solution contains 10 g of H_(2)SO_(4) , normality of the solution is

A 25mL HCl solution containing 3.65g HCl/L is neutralized by 50mL of NaOH solution. Again, 25mL of an H_(2)SO_(4) solution of unknow strenght. The normally of the H_(2)SO_(4) solution is :

Converting mass percent to molarity: the density of a 24.5 mass % solution of sulphuric acid (H_(2)SO_(4)) in water is 1.176 g mL^(-1) at 25.0^(@)C . What is the molarity of the solution? Stregy: Use mass % to calculate number of moles of solute and use density of solution to calculate volume of solution. Describing a solution as 24.5 mass % H_(2)SO_(4) in H_(2)O means that every 100.0 g of solution contains 24.5 g of H_(2)SO_(4) and 75.5 g of H_(2)O . Since we want to calculate the concentration in molarity, we first need to find the number of moles of H_(2)SO_(4) dissolved in a specific mass of solution. Next we use density as a conversion factor to find the volume of that solution and then calculate molarity by dividing the number of moles of H_(2)SO_(4) by the volume of solution.

A solution of oxalic acid, (COOH)_(2).2H_(2)O is prepared by dissolving 0.63 g of the acid in 250 mL of the solution. Calculate (i) molarity and (ii) normality of the solution.
