Answer to Question #95462 in General Chemistry for Faryad pak and Lithuania

Question

11.2g of KOH in 200m of solution. Find molar concentration?

Answer 1

11.2g of KOH in 200m of solution. Find molar concentration?

I assume there is a typo in the text of the problem, and the right version will sound like  “11.2g of KOH in 200 ml of solution. Find molar concentration?”. Because given 200 m is already a molar concentration which should have been found.

In that case:

Mass in 100 ml = 11.2/2=5.6 g

Molecular weight of KOH = 56.1

Molar concentration = mass in 100 ml / molecular weight = 5.6\56.1=0.1 M

0.1 M
