Answer:
0.3
Explanation
The formula to find density is m/v=p
m=mass
v=volume
p=density
---------------------------
All we have to do is plug in 6g and 20cm^3
This will give us 6/20 which simplifies to 3/10
With this you can easily figure out that the decimal for 3/10 is 0.3
So the density of the ice is 0.3
Hope this helped!
