Question

Which of the following is the smallest volume?

500 mL

2500 cm3

5.5 x 10-1 L

25 m3

Answer 1

You'll need your SI prefix conversion ability, plus the conversion between cm^3 and mL (1 cm^3 = 1 mL) to put them all in the same unit. Let's pick mL.

1) 500 mL = 500 mL. That was easy!

2) 2500 cm^3 = 2500 mL (using 1 cm^3 = 1 mL).

3) 5.5 x 10^-1 L = 0.55 L = 0.55 L * (1000 mL/L) = 550 mL

4) 25 m^3 = 25 m^3 (100 cm/m)^3 = 25 x 10^6 cm^3 = 25 x 10^6 mL.
