Answer: The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.
Explanation:
In a crystal, the molecules are closer together as they are in any solid. they have less room to move, and might even be combined together rather than individual
Density = Mass ÷ Volume
D= 30g ÷ 6 cm^3
D= 5 g/dm^3
Glass is not a living organism, so it is <u>abiotic</u>.
