How many atoms are present in 0.25 mole of oxygen?
How many molecules are in a mole of oxygen?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
How many particles does 0.25 mole have?
1 mole of an element contains 6.022*10²³ particles. Hence, 0.25 moles of an element will contain 6.022*10²³*0.25=1.5055*10²³ particles.
