The two biomes which have moderate precipitation levels are savanna and grassland.
Explanation:
An ecosystem includes both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which associates as a system. More importantly, the living things are very modified in the abiotic community because it cannot sustain by itself. Every animal, plant and human needs the primary physiological needs of water, food, and shelter provided by the abiotic system.
A biome is formed of several diverging ecosystems that relate to the community. Biomes can each be deserts, grassland, savanna, tropical rain forest, taiga, boreal and etc.
P2O5 = Phosphorus pentoxide
CuO = Copper (II) oxide
NH4CI = Ammonium Chloride
Mn(OH)2 = Pyrochroite

Answer:
8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.
Explanation:
Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are contained in 1 mole of the compound, 3.26*10²⁵ molecules are contained in how many moles of the compound?
amount of moles= 54.12
Molar mass is the mass of one mole of a substance, which can be an element or a compound. Being the molar mass of the compound Mg(NO₃)₂ 148.3 g/mole, so 54.12 moles of the compound contains 8025.996 grams.
<u><em>8025.996 grams are there in 3.26*10²⁵ Molecules of Mg(NO₃)₂.</em></u>
