The mass of an empty density bottle is 50 g. When it is completely filledwith water, its mass is foundto be 100 g and when itiscompletly filledwith aliquid,its mass is 150 g. The density of the liquid is `"_________"` kg `m^(-3)`.

Options

A. (a) 2
B. (b) 2000
C. (c ) 3.5
D. (c )3500

Answer

B

Explanation

Mass of the empty density bottle,` m_(1)` =50 g
Mass of he bottle with water, `m^(2)` = 100 g
Mass of te bottle with liquid, `m_(3)` =150 g
Volume v = dxxm = 1xx50 = 50 `cm^(3)`
Density ofliquid =
mass of liquid/volume of liquid=`(m_(3)-m_(1))/v=(150-50)/(100-50`
= `100/50= 2 " g "cm^(-3)=2000 " kg "m^(-3)`
