What is the mass of 2.5 mole of water molecules?
The amount of oxygen in 2.5 moles of water is 40 grams. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen.
What is the mass of 3g atom of calcium?
mass of 3 gram C-12=3×1/12=1/4.
How many molecules are in 11g of co2?
11 grams of carbon dioxide consists 0.25 moles of molecules. 0.25 moles= 0.25×6.023×10^23= 1.5×10^23 molecules.
How do you calculate moles of oxygen?
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.
Is O2 16 or 32?
Hover for more information. 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.
How do you calculate grams to moles?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How much is a mole of oxygen?
You can view more details on each measurement unit: molecular weight of Oxygen or grams The molecular formula for Oxygen is O. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Oxygen, or 15.9994 grams.
What is the mass of 2 mole of oxygen atom?
-To calculate the mass of 0.2 moles of oxygen atom we should know the mass of a single atom of oxygen that is 16. -Therefore, the mass of 0.2 moles of oxygen atom is 3.2 grams and the mass of 0.5 moles of a water molecule is 9.0 grams.
