A substance has a volume of 20 mL and a density of 2.5 g/mL. What is its mass?

In all trials, the magnitude of the final velocity for g1 + g2 was less than the magnitude of any initial velocity. as mass increased, what happened to the velocity? the velocity decreased. the velocity increased. the velocity of g1 + g2 could not be measured. the velocity was not affected by the mass increase.

Drag each item into the proper state of matter category.

Which best represents the law of conservation of mass ?
