Which statement is correct for 1 mole of O2?
Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.
What is 5 moles O2?
Therefore, 160 g of oxygen is present in 5 moles.
Is oxygen O2 or just O?
The difference between oxygen (O) and oxygen (O2 )is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen. Oxygen is usually found as a diatomic gas. Therefore, we write it as O2.
How many grams of co2 are produced from the combustion of 100 grams of butane?
We have 100g/(58.1g/mole) = 1.72 moles of butane. Multiply the moles of butane by the molar ratio of CO2/C4H10 (4) to find out many moles of CO2 are produced. If all the butane is combusted (we have plenty of O2), we’ll produce 6.88 moles of CO2.
How many moles are there in 64 grams of O2?
molar mass of oxygen is 16 grams, it means that 1 mole oxygen weighs 16 grams. therefore 64 gram oxygen = 64/16 = 4 mole oxygen. 1 mole of any element contains 6.022 * 10^23 atoms in it.
How do you find moles?
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).
