hopefully this helps :)
<span>2 liters" only shows one significant figure. This "2 liters" can be anything from 1.9 liters to 2.1 liters. Actually, to be more strictly correct, the 2 liters can be between 1.5 liters and 2.4 liters. Either of these bounds would be 2 to the nearest ONE's place.
The biggest percent error would be between 2 and 1.5, which is a volume error of 0.5 liters.
Thus: (0.5/2)*100=25% C: is your Answer</span>
ANSWER - 60%
WORKING OUT
3/5 is equal to 6/10 (doubled)
Which is also equal to 60%
(Each tenth is 10%)
Density= mass/volume 0.492=mass/163.5 mass=0.492*163.5 mass =80.448gram
