Answer:0.50
Explanation:
In carrying out multiplication/division, the answer cannot have more significant figures than either of the original numbers.
500mL has 3 significant figures.
mL is (10 E -3)L=0.010L( 2 significant figures.)
500mL=500*0.010=0.50L(2 significant figures.)
N/B:10E-3=10 raised to the power of -3.
