How many moles are in 50 0 g of o2?

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.

How many moles are in 50 grams of co2?

Explanation: The answer is 44.0095.

How many moles are in 32g of oxygen?

And we know that When the given mass is divided by the molar mass of the gas. We will get the number of moles present in that gas so here it is =1. we get the answer as 1. So the number of moles present in 32 gram of oxygen is 1.

How many moles are in 28g of CO2?

Complete answer:

The molecular weight of a material is required to tell an individual how many grams there are in one mole of that chemical substance i.e. molecular weight of any substance contains 1 mole of that substance. Then 28 g of $C{{O}_{2}}$ contains = 0.636 moles of $C{{O}_{2}}$.

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 of oxygen is present in 640 grams?

therefore 64 gram oxygen = 64/16 = 4 mole oxygen. 1 mole of any element contains 6.022 * 10^23 atoms in it.
