atomic mass=percentage of isotope a * mass of isotope a + percentage of isotope b * mass of isotope b+...+percentage of isotope n * mass of isotope n.
Data:
mass of isotope₁=267.8 u
percentage of isotope₁=90.3%
mass of isotope₂=270.9 u
percentage of isotope₂=9.7%
Therefore:
atomic mass=(0.903)(267.8 u)+(0.097)(270.9 u)=
=241.8234 u + 26.2773 u≈268.1 u
Answer: the mass atomic of this element would be 268.1 u
Answer:
what are the items that have been listed?
Answer:
<em>The correct option is B) Tropical rain forest</em>
Explanation:
The tropical rain forest biome acquires four main characteristics:
1: Increased amounts of rainfall in a year
2: high average temperatures
3: soil that is not enriched with nutrients
4: increased level of biodiversity.
Extreme levels of biodiversity can be seen in the tropical rain forest biome. Hence, due to increased biodiversity, this biome has multistory communities. This biome contains about 50% of the world's known animal and plant species.
