A bottle contains 4.55cm^3 of a metallic solid. The total mass of the bottle and solid is 36.66g.?

Question

The empty bottle weighs 13.95g. What is the density of the solid?

Answer 1

Its a plug in problem, and not a difficult one. Write it out:

4.55 ml solid

36.66g = bottle + solid

13.95 g = solid

Subtract the weight of the bottle and solid from the weight of the bottle.

33.66g - 13.95g = weight of solid in grams

then density = mass/volume

density = g of solid/4.55 ml

Pull out your calculator and plug in the numbers.

Answer 2

JJ, learn the science.  The difference in mass is the mass of the solid.  Mass divided by volume is density.
