What volume of liquid `A_(2)O_(3)` has same number of atoms are there are atoms in `BO_(2(l))` having volume 20 ml ? [Given Density of `A_(2)O_(3)`=1.5 gm/ml and density of `BO_(2)`=0.7 gm/ml, Atomic mass of A =50, Atomic mass of B =60 and O represents oxygen]

Answer

9

Explanation

For `BO_(2)`
`n_("atom")=14/92xx3`
For `A_(2)O_(3)`
`W/14xx5=14/92xx3`
W=13.5 gm
`d=W/V`
`1.5=13.5/V`
`V=13.5/1.5 =9 mL`
