To find how many atoms are in the compound, we first have to find how many moles there are. The numbers in the subscript tell you how many moles of each element are present in the compound. Therefore, to find the number of total moles, we can add up each of the numbers in the subscript:
Cu₂Mg₁H₁O₁ *when there is no number under an element, it is implied that there is 1 mole of the element
2+1+1+1=5 moles
We can then use Avogadro's number and dimensional analysis to find how many atoms are in the compound (Avogadro's number is 6.02x10^23):
5 moles (6.02x10^23/1 mole)= 3.01x10^24 atoms
Answer:
well there are many ways to prevent a pest infestation ..... as we all know ... insects such as ants love leftovers, so store food in airtight containers like Tupperware or jars with rubber seals on the lids.
Keep a tight lid on your trash can at all times and move the trash to an outside dumpster as soon as possible.
Clean your counter tops, tables, and floors on a regular basis to prevent crumbs or food buildup

Answer:
4. Water from upland areas often carries sediment and pollutants. The marshy land and plants in estuaries filter these pollutants out of the water. The plants in estuaries help prevent shoreline erosion. Estuaries also protect inland areas from flooding and storm surges.
5. Dredging impacts marine organisms negatively through entrainment, habitat degradation, noise, remobilization of contaminants, sedimentation, and increases in suspended sediment concentrations.

Answer:
Avogadro's number or Avogadro's constant.
