It's a simple problem but I just can't figure it out...
Please format like: (a) = .002

Very small crystals composed of 1000 to 100,000 atoms, called quantum dots, are being investigated for use in electronic devices.
(a) Calculate the mass in grams of a quantum dot consisting of 1.100 104 atoms of silicon.
_ g

(b) Assuming that the silicon in the dot has a density of 2.3 g/cm3, calculate its volume.
_ cm3

(c) Assuming that the dot has the shape of a cube, calculate the length of each edge of the cube.
_ nm
