The diameter of a single carbon particle in a sample of printer toner is 25nm. If you have 50g of that carbon, how long of a chain of carbon particles could you string end to end? Assume that the particles are perfect spheres and they all have the same diameter. Volume of a sphere: (4/3)πr3 Density of carbon: 2.0g/cm3 The given information and your knowledge of metric prefixes and conversions is the only information that you will need to solve the problem.

The proton has a radius of approximately 1.0x10^-13 cm and a mass of 1.7x10^-24 g. Determine the density of a proton. For a sphere V = (4/3)pi^3

Substance A has a density of 0.30 g/ml and substance B has a density of 0.690 g/ml. Are the particles in substance A farther apart, closer together or separated by the same distance as those in substance B?

You just measured a metal cylinder and obtained the following information: mass = 3.543 g diameter = 0.53 cm height = 4.4 cm Determine the volume (V) and density of the cylinder. (V=nr2 h, where r = radius, h = height, π = 3.14) S A Volume of the cylinder = 0.87 cm3; density of the cylinder = 3.7 g/cm3 B Volume of the cylinder = 0.97 cm3; density of the cylinder = 2.7 g/cm3 C None of the above have both the volume and density correctly reported E Volume of the cylinder = 0.97 cm3; density of the cylinder = 3.7 g/cm3 Volume of the cylinder = 0.87 cm3; density of the cylinder = 2.7 g/cm3

A brick of a certain metal has area on top of 3.54 cm x 6.93 cm. It has mass 921 g. How high is the brick in cm? The metal has density of 10.6 g/cm3 2.54 cm = 1 inch Ixhxw-V V- m/d You need to combine the above equations; this is a typical math skill you need in chemistry.
