1.

Which among the following has minimum molarity ?

Answer»

20 g of `NaOH` in 100 mL solution
24.5 g of `H_(2)SO_(4)` in 500 mL solution
14 g of `HCl` in 100 mL solution
37 g of `Ca(OH)_(2)` in 2000 mL solution

Solution :Molarity `= 37/74 xx 1000/2000 = 0.25`
37 g of `Ca(OH)_(2)` in 2000 mL solution has MINIMUM molarity.
