To find the answer do the following:
(1) Convert mg to g by dividing by 1000 (1g = 1000mg).
(2) Divide the number of grams by 32 (there are 32g of O2 in one mole of O2).
(3) The answer is 0.0000078 = 7.8E-6 mole. Step three may not be intuitive. If you divide an amount of a substance in grams by the substance's atomic weight, that tells you how many moles of that substance you have.

(very much the same as: How many WhatSoEver in a dozen (12) or gross (144)
In 0.25 moles = 0.25*6.02*1023 = 1.5*1023molecules O2

PV = nRT
(1 atm)(X V) = (0.25 moles O2)(0.08206 L*atm/mol*K)(298.15 K)
= 6.1 Liters oxygen in volume
