How many moles of sulfur trioxide will be produced when two moles of sulfur combine with three moles of oxygen?
One mole of sulfur reacts with 1.5 moles of oxygen to produce one mole of sulfur trioxide. So, with two moles of sulfur and three moles of oxygen, the limiting reactant is sulfur. Therefore, two moles of sulfur will produce two moles of sulfur trioxide.
How many moles of oxygen are there in one mole of hydrogen peroxide?
In one mole of hydrogen peroxide (H2O2), there are two moles of oxygen atoms.
How many grams of oxygen wil be in two moles of potassium dichromate?
In potassium dichromate (K2Cr2O7), there are 7 oxygen atoms per molecule. Therefore, two moles of K2Cr2O7 would contain 14 moles of oxygen atoms. Each mole of oxygen atoms has a molar mass of approximately 16 grams, so there would be 224 grams of oxygen in two moles of potassium dichromate.
What is the volume of oxygen occupied by two moles at 1.3 ATM pressure and 300 k?
PV = nRTV = nRT/P = (2moles)(0.0821 Latm/Kmol)(300K)/1.3 atm V = 37.9 liters = 38 liters (2 significant figures)
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O

4 moles of oxygen atoms are present in 4 moles of H2O
Why volume of hydrogen should be twice the volume of oxygen formed?
The volume of hydrogen should be twice the volume of oxygen formed in the electrolysis of water because the ratio of the number of moles of hydrogen to oxygen in water is 2:1. This is based on the molecular formula of water, H2O, where each water molecule contains two hydrogen atoms and one oxygen atom.
Which best represents the number of moles in exactly 64 grams of oxygen (O2)?
The number of moles in exactly 64 grams of oxygen (O2) is two.
What is 42 grams of diatomic oxygen in moles?
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
How many moles are in 64 g of oxygen?
4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2
He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
In 2 moles of potassium dichromate, there are 16 moles of oxygen atoms (from the two oxygen atoms in each formula unit). The molar mass of oxygen is 16 g/mol, so in 2 moles of potassium dichromate, there are 32 grams of oxygen.
How mony moles of oxygen atoms do 1.5 moles of Co2 contain?
0.75 moles of any substance is 0.75(6.02x1023) = 4.52x1023 particles. If those particles are CO2 molecules, and each molecule has 2 oxygen atoms, then it's 2(4.52x1023) = 9.04x1023 oxygen atoms.
2 H2 plus O2 2 H2O - How many moles of water will be produced from a fuel cell that consumes 0.633 moles of oxygen?
For every mole of oxygen consumed in the reaction 2H2 + O2 -> 2H2O, two moles of water are produced. Therefore, if 0.633 moles of oxygen are consumed, the number of moles of water produced would be 2 x 0.633 = 1.266 moles.
