A typical sugar cube has an edge length of 1.0 cm. If you had a cubical box that contained 1.7 mol of sugar cubes, what would its edge length be? (One mole = 6.02 x 1023 units.)

    data.
    -sugar cube edge of length = 1.0cm
    -moles of sugar cubes =1.7moles
    -edge length = unknown
    -one mole =6.02 × 10^23 (consitant)
    solution
    let length of the edgebox =Y
    hence,from volume of cubical box,V= 1.7mole of sugar cube × 6.02 × 10^23 × 1cm
    V = 1.0234 × 10^24cm^3
    from V = Y^3
    Y^3 = 10234 × 10^20
    =2.17 × 10^21 Km
