Question

how much amount of koh is required to prepare 0.1m koh solution in 100 ml of distilled water​

Answer 1

☑ 0.57gram koh

Given :

Concentration of Koh is 0.1M in 100ml of distilled water

To find :

Amount of Koh required to prepare 0.1M Koh Solution in 100ml distilled water

Explanation :

first we have to convert 100ml into litres

100ml = 0.1litre

Concentration = 0.1M

We have to find the moles of Koh :

$concentration = \frac{moles}{litre}$

$0.1m = \frac{moles}{0.1litre}$

$0.01moles = no \: of \: moles \: of \: koh$

Molar mass of Koh = 40+16+1 = 57

Moles = given mass / molar mass

0.01moles = Mass / 57

Mass = 0.57gram (Koh)
