How many molecules are in 48 grams of oxygen gas?
Alinara [238K]

Answer:

Since oxygen (O) has an atomic mass of 16 g, oxygen gas (O2) has a molecular mass of 2 x 16 = 32 g. We need to convert the given amount of oxygen gas to moles and this can be done by dividing the given mass by the molecular weight of oxygen gas. Hence, moles of oxygen gas = 48 g / 32 g/mole = 1.5 moles.
