How many moles are in O2?
One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
What number of moles of 02 is needed to produce 14.2 grams of P4O10?
Hence, 0.25 mole of O2 is needed to produce 14.2 grams of P4O10 from P.
How do you calculate the number of moles needed?
Determine the moles of product produced by dividing the grams of product by the grams per mole of product. You now have calculated the number of moles of every compound used in this reaction. 41.304 g of NaCl ÷ 58.243 g/mol = 0.70917 moles of NaCl.
How many oxygen atoms are in 4.0 moles of O2?
Oxygen gas (O2) is made up of 2 atoms of oxygen. 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.
How many moles are in 16g of O2?
16 g i equal to 0.5 mole of oxygen molecule. we know in one molecule of oxygen there are 2 atom. Hence in 0.5 mole of oxygen molecule, there are 0.5 * 2 mole of atom of oxygen.
How many moles of O2 are needed to produce 75 grams of P4O10 from P4O10 284 g mol?
(75g)/(284g. mole) = 0.2641 moles [the g cancles and moles moves to the top]. Rounded to 2 significant figures (since 75 is only 2 significant figures), the number of moles of P4O10 is 0.26. The equations says we need 5 moles of O2 for every mole of P4O10.
What volume of O2 is required?
What is the volume of O2 required at STP for the oxidation? ⇒ 22.4 L of O2 is required for the oxidation of 22.4 L of SO2.
How many grams of calcium nitrate CA No 3 2 contains 24 grams of oxygen atoms?
Question: Question: How many grams of calcium nitrate, Ca(NO3)2, contains 24 grams of oxygen atoms? Answer: 41 gramsHelp: please show me step by step on how to arrive at answer above. thanks.
How many moles of O2 can be produced from 12 moles KClO3?
How many moles of O2 can be produced by letting 12.00 moles of KClO3 react? The KClO3 / O2 molar ratio is 2/3. 2 mol KClO3 / 3 mol. O2 = 12.00 mol KClO3 / x = 18.00 mol.
What is the mole formula?
Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).
How many moles of O2 are needed to produce 12 moles?
To produce 12 moles of water 6 moles of oxygen gas are needed.
How many moles of O2 are needed to produce 4 moles H2O?
So, the 4 moles of hydrogen reacts with 2 moles of oxygen, to give 4 moles of water.
How many moles of O2 are needed to completely react with 4.0 moles C2H6O?
Thus we can write the conversion factor, 4.0 moles of C2H6O will react with = 4.0 mole of C2H6O = 12 mole of O2Thus 12 moles of O2 are needed to completely react with 4.0 moles of C2H6O.
