Answer:
1.48381734165x 10²⁵ molecules
Explanation:
1 grams CuNo3 is equal to 0.0011897028836018 mole.
x = 5.5 moles
x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018
4623.003grams
the molar mass of cuno3 =187.56 = 6.02 x10²³
4623.003g = x
187.56x = 4623.003 x 6.02 x10²³ = 27830.47806 x10²³ = 1.48381734165x 10²⁵
Answer : Option C) Mammalia
Explanation : The most specific classification that puts humans in the same category of yapok is mammalia. As humans are also mammals which feeds on their young ones with milk, yapok also does the same. This characteristics makes them similar.
As from the definition of mammal, it is any of a class (Mammalia) which has warm-blood mostly higher vertebrates like placentals, marsupials, or monotremes which are seen to nourish their young with milk secreted by mammary glands, and they have the skin which is usually more or less covered with hair, and it also include humans.
