Solution

The correct option is B
$900$

Given data :
The relative density of ice is $0.9$
The density of ice=?
Formula:
$R e a l a t i v e d e n s i t y = \frac{d e n s i t y o f i c e}{d e n s i t y o f a i r} d e n s i t y o f a i r = 1000 \frac{k g}{m^{3}}$
solution:
$0.9 = \frac{d e n s i t y o f i c e}{1000} d e n s i t y o f i c e = 0.9 \times 1000 \frac{k g}{m^{3}} d e n s i t y o f i c e = 900 \frac{k g}{m^{3}}$
So, the correct option is C.
