If you have a density of 100 kg/L, and a mass of 1000 units, tell me the following: First what are the mass units?

The mas unit is the the 'Kilogram' written as 'kg'

Volume is 10 L

Explanation:

The complete question is

If you have a density of 100 kg/L, and a mass of 1000 units, tell me the following: First, what are the mass units?

Second, what is the volume

mass units is the 'Kilogram', written as 'kg'

density = mass/volume = 100 kg/L

the mass  = 1000 kg

volume = mass/density = 1000/100 = 10 L

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
