To calculate the number of moles of oxygen in 2.50 mol of magnesium phosphate (Mg3(PO4)2), we first need to determine how many moles of oxygen are present in one mole of magnesium phosphate.
The formula indicates that there are 2 phosphate ions (PO4) in one molecule of magnesium phosphate, and each phosphate ion contains 4 oxygen atoms. Therefore, there are 2*4 = 8 oxygen atoms in one molecule of magnesium phosphate.
Since we are given 2.50 mol of magnesium phosphate, we can multiply the number of moles by the number of oxygen atoms in one mole to find the number of moles of oxygen:
2.50 mol * 8 mol of oxygen/mol of magnesium phosphate = 20 mol of oxygen
Therefore, there are 20 moles of oxygen in 2.50 mol of magnesium phosphate.
The chemical formula for magnesium phosphate is Mg3(PO4)2
