How many atoms are in a cubic inch?

Answer 1

To calculate the number of atoms in a cubic inch, we first need to determine the volume of a cubic inch, which is approximately 1.64 x 10^-5 cubic meters. Next, we need to convert this volume to cubic centimeters, which is 16.39 cubic centimeters. Using the Avogadro's number, which is 6.022 x 10^23 atoms/mol, we can then calculate that there are approximately 2.47 x 10^22 atoms in a cubic inch.

Answer 2

This involves a lot of steps, so bear with me. First, you need to convert in3 to cm3 (remember to cube the numbers as well as the units!) to mL (1 cm3 = 1 mL, that's just a definition), since chemistry uses mL as the standard unit for volume. Next, water almost always has a density of 1.0 g/mL, so use that to convert to mass. Then, use the molar mass of water (18.0158 g/mol) to convert to moles so that you can use Avogadro's Number (6.02 x 1023 molecules/mole) to finally find molecules.

(1 in3) x (2.543 cm3/in3) x (1 mL/1 cm3) x (1.0 g/mL) x (1 mol/18.0158 g) x (6.02 x 1023 molec/mol) = approximately 5.48 x 1023 molecules of water

Answer 3

0. A square inch is a two dimensional object, which has no depth.

Answer 4

There are approximately 1.66 x 10^24 atoms in a cubic inch.
