If a tank of water is being drained at a rate of 20.0 cm3/sec, what is the rate in liters/min ?

Question

10-3 m3 = 1 L

Answer 1

Your given conversion is better translated as 1000 cm^3 = one L.

In solving conversions, make sure you write out the units. It will be most helpful.

so, (20 cm^3 )/sec X ( 1 L/1000 cm^3) x (60 sec/ 1 min)

= cross out the units and you get 20 x 60 L/ 1000 min

or 1200/1000 or 1.20 L/min (note sig fig)

Answer 2

Remember: 1 cm^3 = 1mL = 1*10^03 L
1 sec = 1/60 min

Answer 3

ya you really do need help
it would be 20x60/1000=1.2L/min
