Question

calculate the no of gram atom and gram molecule in48g of oxygen

Answer 1

Moles of O2 = mass/Molar mass = 48/32 = 1.5mol

Molar mass of O2 = 32g/mol

Number of gram molecules

1 mole of any molecule contains Avogadro number of molecules

Number of molecules of O2 = moles X Avogadro number

Number of gram molecules of O2 = 1.5 X 6.022 X 1023= 9.03 X 1023 gram-molecules

Number of gram atoms of O

1 molecule of O2 contains 2 atoms of O

9.03 X 1023 gram-molecules of O2 contains 2 X 9.03 X 1023 or 1.806 X 1023 gram-atoms of O
