the mass of one mole of a substance is 4.65 x 10-23 gm.what is the molecular mass of the substance?what could be this substance?
Mass of 1 mole of substance = 4.65 x 10-23 gm
Molar mass = Mass * Avogadro number
Molar mass = 4.65 x 10-23 gm * 6.023 * 1023
Molar mass = 28
So, element is = N2 (diatomic)
