NO OF MOLECULES PRESENT IN 8g OF KNO3

Answer»

Lets find out


Firstly determine the molar mass of POTASSIUM nitrate[KNO3]


39.1 + 14 + 3(16) = 101.10


Then simply divide mass/molar mass of KNO3


Mass of KNO3 = 8G

Molar mass of KNO3 = 101.10

No. of molecules = 0.079


0.079 moles are present in 8g of KNO3
