Question from Jordan, a student:
In Chemistry we are doing a lot of problems that are much more math related than anything. One of my questions reads: A certain medallion has a mass of 55.64 g. When placed in 75.2 mL of water in a graduated cylinder,
the water level rises and then reads 77.8 mL.
Is the medallion made of platinum (D=21.4 g/mL) or silver (D= 10.5 g/mL)?
This is due tomorrow, and I've already given up on actually getting this worksheet done, so all i really want to know is how to work out a problem like this. I don't even know where to begin, my teacher is about worthless to put it nicely. I have a test over this on Monday and I just really want to know how to work problems like these. Like how can i tell the density by how much water is displaced...oh idk. I just need help please. thank you
