6 0

Explanation:

Carbon exists in several isotopes. ... Carbon has the atomic number of 6 which means that all isotopes have the same proton number. However, the number of neutrons is different, thus giving different mass numbers. Carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 contains 8 neutrons.

A cube of tin that is 112 mm on each side has a mass of 8.21 grams. A single tin atom has a mass of 118.7 amu. How many tin atom
Sveta_85 [38]

Answer:

4.17e+22 atoms of tin are present in the cube

Explanation:

We don't require the size of the cube. With the mass and the molar mass of tin = 118.7 amu we can find moles of Tin. As 1 mol = 6.022x10²³ atoms we can find the number of atoms:

<em>Moles Tin:</em>

8.21g * (1mol / 118.7g) = 0.0692 moles Tin

<em>Atoms Tin:</em>

0.0692 moles Tin * (6.022x10²³ atoms / mol) =

<h3>4.17e+22 atoms of tin are present in the cube</h3>
