Need help with some basic science-density questions

[bladder23]

2 questions

1) An empty bottle has a mass of 35.5 g. When this bottle is completely filled with water it has a mass of 65.5 g. When this bottle was filled with another liquid, ethanol, it has a total mass of 51.5. Find the density of the ethanol

2) 60 mL of a certain liquid has a mass of 72g. A block of mass 172g of a solid material has a volume of 75 cm cubed. Would this block float in liquid? Prove your answer.


Any help is greatly appreciated!

I think you gotta show some effort first if you want to get someone to help you. I've noticed that when you ask for help, you will generally get a better response if you work through the problem and point out where you are having trouble.
