A typical atom has a diameter of about 1.0×10^−10m. Approximately how many atoms are there along a 9.5 −cm line?
A typical atom has a diameter of about 1.0×10^−10 m. Approximately how many atoms are there along a 9.5 −cm line? I got the first one correct, but I got the second one wrong. I put 9.5x10^10 and it wasn't correct. Is it 9.5x10^8?
Here is the problemA typical atom has a diameter of about 1.0 X 10^-10m. What it is in inches?How many atoms are there along a 1.0 cm line?( I got the first part but confuse w/ the second part. how do I know how many atoms are there? Please help me)

The nucleus of the hydrogen atom has a radius of about 1.0 × 10-15 m. The electron is at a distance of about 5.29 × 10-11 m from the nucleus. Assuming the hydrogen atom is a sphere with a radius of 5.29 × 10-11 m, find (a) the volume of the atom, (b) the volume of the nucleus, and (c) the percentage of the volume of the atom that is occupied by the nucleus.
Consider a 1.0 km section of a city water line that is 30 cm in diameter. (a) Find the difference in pressure between each end of the pipe, assuming the volume rate of flow of water is 700 cm. (b) Assuming the same pressure difference found in part (a), find the volume rate of flow, and average velocity, of molasses, which has a viscosity of around 100 Poise.
