This is my science homework but it's more math than science...please help.
As shown in the following diagram, an empty 1,000mL container has a mass of 250g. When filled with a liquid, the container and the liquid have a combined mass of 1300g.
Empty : 250.0g Filled:1300g
What is the density of the liquid?
(1)1.00 g/mL
(2)1.05 g/mL
(3)1.30 g/mL
(4)0.95 g/mL
(P.S. I'm not sure how to show the diagram so it might be in the comments...if I figure it out).

cwrw238 · Answer

the mass of the liquid = mass of filled container - mass of empty container

cwrw238 · Answer

density = mass of liquid / volume of container
