5.00cm3 of hydrogen peroxide bleach released 74.4 cm3 of oxygen gas. Under the experimental conditions used,1 mole of the gas molecule has a volume of 24.8 dm3. Calculate how many moles of oxygen were released.
There is no conc to calculate moles

One mole of any gas in standard conditions has 24000 cm3 volume so one you can use the equation moles=volume/24000

1 mole has a volume of 24.8 dm3
So how many moles are in 74.4 cm3
(Watch your units)

Moles = 74.4 / 24,000 = 3.1 x10^-3 moles
