Answer 1

1) 0.5 mole of oxygen gas = 2 x 1/2 mole of oxygen atom

1 mole of oxygen = 16 g.

This is because one molecule of oxygen gas has two atoms of oxygen.

2) 3.011 x 10^23 atoms of oxygen= 1/2 mole of oxygen

= 16/2 g

= 8g.

3) 6.022 x10^24 molecules of oxygen

= 6.022 x 10^23 x 10 molecules of oxygen.

= 1 x 10 moles of molecules of oxygen

= 10 moles of molecule of oxygen

= 10x 2 x16 g

= 320g.

Hope this helps.
