10 moles of oxygen atoms or 5 moles of oxygen molecules.
4.7141x10^24 moles
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
2KClO3 + heat -> 2KCl + 3O2 14 moles KClO3 (3 mole O2/2 mole KClO3) = 21 moles oxygen made This is a common industrial method of producing oxygen.
0.100 moles silicon (SiO2 ) dioxide (2 mole O/1 mole Si)(6.022 X 1023/1 mole O) = 1.20 X 1023 atoms of oxygen ======================
Take the balanced equation. CH4+2O2---->CO2+2H2O.So two moles are consumed
14.0 g x 1 mole/187.56 g = 0.0746 moles0.0746 moles Cu(NO3)2 x 6 moles O/mole Cu(NO3)2 = 0.448 moles O atoms0.448 moles O atoms x 6.02x10^23 atoms/mole = 2.70x10^23 atoms of oxygen
1 mole CaCO3 (3 mole O/1 mole CaCO3) = 3 moles oxygen
0.125 mole
12.8 grams oxygen (1 mole O/16.0 grams) = 0.800 moles of oxygen
Zero
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
1 mole N2O3 (3 moles O/1 mole N2O3) = 3 moles oxygen atoms ==================
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 0.000831 mole of CO2 will have 0.000831 mole of carbon atoms.
71/284 = x / 4 x = 1 mole
2KClO3 + heat -> 2KCl + 3O2 14 moles KClO3 (3 mole O2/2 mole KClO3) = 21 moles oxygen made This is a common industrial method of producing oxygen.
2C2H2 + 5O2 ---->4CO2 + 2H2O so 1 mole of acetylene (ethyne) reacts with 2.5 moles of oxygen. Answer 2.5 moles
1 mole.
