Final answer:
In 100 moles of CH₃(PO₄)₂, there are 100 moles of carbon, 300 moles of hydrogen, 200 moles of phosphorus, and 800 moles of oxygen.
Step-by-step explanation:
To determine how many moles of each element are present in 100 moles of CH3(PO4)2, we must first understand the composition of the compound. The chemical formula indicates that for each mole of the compound, there is 1 atom of carbon (C), 3 atoms of hydrogen (H), 2 atoms of phosphorus (P), and 8 atoms of oxygen (O). Therefore, to find the number of moles of each element in 100 moles of the compound, we simply multiply the number of atoms of each element found in one mole of the compound by 100.
For carbon (C), there is 1 mole of carbon in one mole of CH3(PO4)2, thus in 100 moles of the compound, there are 100 moles of carbon. Similarly, for hydrogen (H), there are 3 moles of hydrogen in one mole of the compound, resulting in 300 moles of hydrogen in 100 moles of CH3(PO4)2. For phosphorus (P), there are 2 moles of phosphorus in a mole of the compound, equating to 200 moles of phosphorus in 100 moles of CH3(PO4)2. Lastly, as there are 8 moles of oxygen in one mole of CH3(PO4)2, this translates to 800 moles of oxygen in 100 moles of the compound.
