What is the mass of the rock? 35mL 545.2g
4) Which has more volume: 1000cm3 of feathers or 250mL of soda 4) Which has more volume: 1000cm3 of feathers or 250mL of soda. Explain your answer. Since cm3 and mL are the same units for volume, I can cross them out and compare the numbers. Since 1000 is larger than 250, the feathers have the higher volume.
