Question

How many grams of KNO3 are present in 185 mL of a 2.5M
solution?

Answer 1

Hey mate

The molar mass of kno3 is 100

We have to find grams of kno3

So by using formula of molarity we can find it

MOLARITY = Given mass upon

Molecular mass that is moles upon liters of solution

molarity = 2.50×0.185×100 = given mass

46.25

Hope this helps u
