Interpretation Introduction

Interpretation:

From the given mass of isopropanol, number of hydrogen atoms in isopropanol has to be calculated.

Concept Introduction:

  • Molar mass of a molecule can be calculated from its molecular formula by taking the sum of atomic masses of all the elements present in it.
  • Conversion formula for mass of a molecule into number moles,

Numberofmoles=MassingramsMolarmass

  • Each mole contains Avogadro number of atoms. 1mol=6.022×1023atoms
  • Number of atoms from given number of moles is calculated as,

    Atoms=6.022×1023atoms1mol×Number ofmoles
