How Many Atoms Are You? Estimate the number of atoms in the body of a 50 kg physics student. Note that the human body is mostly water, which has molar mass 18.0 g/mol, and that each water molecule contains three atoms.
A hollow spherical container has an outer diameter of 10.50 cm. The thickness of the walls is 0.50 cm. The container is filled with water. Water molecules are approximated to be spheres with a diameter of 275 pm. How many water molecules are present inside of the container? Your answer needs to have the correct number of significant figures.
Avagadro's number (6.023 × 1023) is a pure (unitless) number which serves as a good standard for measuring the number of molecules in ideal gases at STP.
A)What is the volume, in cubic kilometers, of Avogadro’s number of sand grains, if each grain is a cube with an edge length of 1.3 mm and the cubes are densely packed (with no air between them).
B) How long, in kilometers, would a beach have to be for this sand to cover it to a depth of 10.0 m? Assume a beach is 100.0 m wide, and you can neglect the air spaces between the grains.
