dsf
Step-by-step explanation:
It is known that density is the amount of mass present in per liter of a substance. 
Mathematically, Density = 
 
 
It is given that mass is 2.75 kg or 2750 g (as 1 kg = 1000 g) and volume is 250 
 .
. 
Therefore, calculate the density of substance as follows. 
 Density = 
 
 
 = 
 
 
 = 11 
 
 
Thus, we can conclude that density of given substance is 11
