Question

in 500ml solution, 20.7g potassium carbonate is dissolved. calculate its morality ​

Answer 1

Answer:

Now what is morality??

Anyways..it's molarity

Explanation:

M= n(moles of solute)/V(volume of solution in ml)×1000

Now K2CO3 has weight of 138

So required moles are 20.7/138 = 0.15

So,M = (0.15/500)×1000 = 0.30M

Answer 2

Answer:

Molarity=no. Of moles of solute/volume of solution(ml) *1000
