How many kilograms of salt water, (with a density of 1.20 g/cm^3) are needed to fill an aquarium that measures 125.0 ft^3? (Hint: Density can be used as a conversion factor to convert volume to mass.)(Remember to make use of significant figures.)

Question

I haven't the slightest clue as to how to solve this. Any help would be immensely appreciated.

Answer 1

density = mass / volume
so,
mass = density * volume

you just have to convert your units
