ANSWER:
Solution :Step 1 : -10Given, atomic radius of neon(Ne) = 0.69 Å = 0.69 ×10 m. Volume of atomic sphere = 4 r . 3 Fraction of space that Ne atoms occupy at STP = One mole of gas contains Avogadro number of gas molecules, which is equal 6.023×10 23So, now let’s calculate the total volume of neon : 4 3 Vn 3 r = 4 × 22 ×( 0.69 ×10 -10) ×6.023×10 m . 3 3 7
