Question

How many moles of magnesium phosphate, Mg3(PO4) 2 will contain 0.25 mole of oxygen atoms ? A) 0.02 B) 3.125*10^-2 C) 1.25*10^-2 D) 2.5*10^-2

Answer 1

Answer:

Means one moles of magnesium phosphate contains 8 moles of oxygen atoms. - Then how many moles of magnesium phosphate contain 0.25 moles of oxygen. - Therefore 0.03125 moles of magnesium sulphate contains 0.25 moles of oxygen.
