Question

HOW TO FIND MASS OF ELEMENT PRESENT IN ONE MOLE OF COMPOUNDS ​

Answer 1

Answer:

Explain

no of mole=mass in gram/molar mass

n = mass/molar mass

no mole =1

• so, mass in gram = no of moles × molar mass

eg: find mass of 1 mol of  O2

    n=mass/molar mass

    mass=n×molar mass

            =1×32 (molar mass of o2 =32)

             =32g
