How many o atoms are in 1.25 mol of so2

The number   of  O atoms  that ate in 1.25  mol   of SO2  is  2.5  moles

  calculation

moles of O= total number O atoms in SO2    x  1.25  moles

The number  of  O  atoms in SO2 =   1  x2 = 2 atoms

moles is therefore=   2  x 1.25 moles = 2.5 moles

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
