You know from the chemical formula that 1 mole of Cu3(PO4)2 contains 2 moles of P so you can work out how many moles of P are in 8.1 moles of Cu3(PO4)2.
<span>As for anything, 1 mole of X contains 6.022 * 10^23 of X. Multiply moles of X by Avogadro's number.</span>

<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.
Answer:
Fisheries science. This discipline aims to study and understand fisheries biology, food web, the predator-prey relationship, stock status information, as well as the socioeconomic status of fishermen (commercial and substantial)
Explanation:
The information from this discipline will help environmental scientists understand why there is a decrease in fish in the ocean. The reasons can vary from over fishing to decline in the reproduction of fishes due to climate change.
