How many grams of water (H_2O) have the same number of oxygen atoms as 1.0 (mol} of oxygen gas?

atomic mass of H is 1 and O is 16,
so H2O has a molar mass of 18.
Oxygen gas is O2, with a molar mass of 32. So 1.0 mole of oxygen gas has 6.02x10^23 molecules = 12.04x10^23 oxygen atoms. how do i go further?

No, you are given a mole of oxygen atoms, not oxygen gas. One mole of oxygen atoms O makes 1/2 mole of O2

H2O means two H atoms for each O atom. So if you have a mole of O, you must have two moles of H.
You then have one mole of H2O

mass= mass H2 + mass O= 2+16=18
