how many moles of oxygen atoms are in one mole of the molecule Ca5(PO4)3OH? could you also show work

13 moles of oxygen

Explanation:

A mole of a substance is the unit of measuring the number of particles within a chemical substance.

The given compound is:

      Ca₅ (PO₄)₃OH

This is a mole of   Ca₅ (PO₄)₃OH

  In this compound we have:

  5 moles of Ca

  3 mole of P

   13 mole of O

   1 mole of H

So,

  In 1 mole of  Ca₅ (PO₄)₃OH, we have 13 moles of oxygen

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
