What is the mass of an aluminum cylinder that has a volume of 1.50m3

Aluminium density: 2700g/m^3

therefore; 2700g/m^3 X 1.50m^3 = 4050g = 4.05Kg

Just use the units of density (mass/volume) and the units of what's given to figure it out :)

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
