Why are units used that are to express the densities of gases different from those used to express the densities of solids or li
quids
1 answer:
If the units for gases were the same as the units for numbers would be too small to be convenient.
For example, the density of iron is 7.87 g/cm³.
Using the same units, the density of hydrogen is 0.000 0899 g/cm³.
It is much more convenient to express the density in numbers that are easier to visualize: 0.0899 g/L, and that is still a small number.

Answer:
how tall each sibling is
Explanation:
To find average atomic mass you multiply the mass of each isotope by its percentage, and then add the values up.
35 * 0.90 + 37 * 0.08 + 38 * 0.02 = 35.22
Average atomic mass closest to 35.22 amu.
