    (a)

    To determine:

    Convert 3.5×1014cm3molecule1s1 to L mol1s1.

    Explanation of Solution

    1cm3=11000L

    1molecule=16.022×1023mol

    3.5×1014cm3molecule1s1=3.5×1014cm3molecule.s=3.5× 10 14×( 1 1000 L)( 1 6.022× 10 23 mol)×s=3.5× 10 141000×6.022×1023Lmol1s1=3.5×6.022×106=2.1×107Lmol1s1

    Interpretation Introduction

    To determine:

    Find the value of 7.1×1018cm3molecule1s1 to L mol1s1

    Explanation of Solution

    1cm3=11000L

    1molecule=16.022×1023mol

    7.1×1018cm3molecule1s1=7.1× 10 18cm31molecule×sputing the value you get=( 7.1× 10 18 )×( 1 1000 L)( 1 6.022× 10 23 mol)×( 1s)=7.1× 10 18×6.022× 10 231000 Lmol.s=4.275×103Lmol1s1=4.3×103Lmol1s1.

    Interpretation Introduction

    To determine:

    Convert 6.1×1030

    molecule1s1 to L mol1s1

    Explanation of Solution

    1cm3=11000L

    1molecule=16.022×1023mol

    6.1×1030cm3

    molecule1s1

    =6.1×1030cm3molecule.s=6.1× 10 30×( 1 1000 L)( 1 6.022× 10 23 )mol.s=6.1× 10 30×6.022× 10 231000Lmol1s1=3.7×109Lmol1s1.

    Conclusion

    Conversion factor to convert cm3

    molecule1s1 to Lmol1s1 is 6.022×1020
