Question

convert into grams 4 moles of oxygen atom​

Answer 1

Explanation:

Since oxygen has an atomic mass of 16 g/mole, the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole. Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.
