Ar of O = 16g/mol
Mr of O2 = 2(16) = 32g/mol
Using the formula : mass = Mr x number of moles
mass = 32g/mol x 50mols = 1600g
It is not measured in grams but PPM because it is a gas.
To find the number of oxygen atoms in 3.120 grams, we need to first calculate the number of moles using the molar mass of oxygen gas. The molar mass of oxygen gas is 32 g/mol. So, 3.120 grams is equal to 0.0975 moles. Each mole of oxygen gas contains 2 oxygen atoms, so there are 0.195 moles of oxygen atoms in 3.120 grams. Finally, using Avogadro's number (6.022 x 10^23), we find that 1.17 x 10^23 oxygen atoms are present in 3.120 grams of oxygen gas.
6,5 moles oxygen equals 208 g.
The answer is 2 moles.
To determine the amount of gas needed to react with 348.5 grams of oxygen, you need to know the balanced chemical equation of the reaction. Then, use the stoichiometry of the reaction to calculate the amount of gas required based on the molar ratio between the gas and oxygen in the reaction.
four moles. Approximately. Oxygen has a molecular weight of 16.0 grams per mole so 64 grams divided by 16.0 grams per mole is four moles.
There are many different ways to calculate the moles and grams of oxygen. but one mole of oxygen is always gonna equal 32 grams because its diatomic, meaning it only comes in nature as O2. so it would be the atomic mass of oxygentimes 2. 16*2= 32
Balanced equation. 4Na + O2 ->2Na2O 14.6 grams Na (1 mole Na/22.99 grams)(1 mole O2/4 mole Na)(32.0 grams/1 mole O2) = 5.08 grams oxygen gas needed --------------------------------------------
In chemistry, the outcome of a reaction must have the same mass as the initial state. This means that if you have 32g of oxygen and 4g of hydrogen, you just have to add the numbers to discover the original mass (in this case, 36g).
To find the number of molecules in 38 grams of oxygen gas, you would first calculate the number of moles of oxygen using the molar mass of oxygen (32 g/mol). Then, you would use Avogadro's number (6.022 x 10^23 molecules/mol) to convert moles to molecules. The final answer would be approximately 3.01 x 10^23 molecules.
The molar mass of oxygen gas (O2) is 32.00 g/mol. Therefore, the mass of 4.00 moles of oxygen gas is 128.00 grams.
The molar mass of oxygen gas (O2) is 32 g/mol. To find the weight of 0.8834 moles of oxygen gas, you would multiply the molar mass by the number of moles: 32 g/mol x 0.8834 mol = approximately 28.27 grams.
