How many molecule are present in 12 L of liquid C `Cl_(4)`? The density of the liquid is 1.59 g `cm^(-3)`?

(a)`7.44xx10^(26)`

(b)`0.74xxX10^(26)`

(c )`1.59xx10^(26)`

(d)`15.9xx10^(26)`

Text Solution

Verified by Experts

The correct Answer is:

`1 c c of C Cl_(4)` contains `1.59 g` of it `=1.59/1.58`
`:. 12 L` of liquid `C Cl_(4)` will contain `=12xx1000xx0.0103`
`implies 0.744xx10^(26)` moles of it
