How many liters of water can be made from 5 L of oxygen gas and an excess of hydrogen?
55 grams O2 × (1 mol O2 ÷ 32 g O2) × (2 mol H2O ÷ 1 mol O2) × (22.4 L ÷ 1 mol H2O) = 77 L H2O(g)In the liquid form, it works out to just under 62 milliliters.
The number of moles of h2o formed when 1 mole of o2 reacts with c5h12 in the reaction c5h12 plus 8o2 equals 5co2 plus 6h2o is?
From the balanced chemical equation, 1 mole of C5H12 reacts with 8 moles of O2 to produce 6 moles of H2O. Therefore, when 1 mole of O2 reacts, it will produce 6 moles of H2O.
What is the balanced equation for The total number of grams of CO2 that are produced when 4 grams of C are added to 10.67 grams of O2?
The balanced equation is: 2C + O2 -> 2CO2. First, determine the moles of C and O2: 4g C / 12 g/mol = 0.33 mol C and 10.67g O2 / 32 g/mol = 0.33 mol O2. From the balanced equation, 2 moles of C produces 2 moles of CO2, so 0.33 mol C will produce 0.33 mol CO2. Since CO2 has a molar mass of 44 g/mol, the total grams of CO2 produced will be: 0.33 mol CO2 x 44 g/mol = 14.52 grams of CO2.
Calculate the number of atoms of O contained in 16.0 pounds of O?
To calculate the number of oxygen atoms in 16.0 pounds of oxygen, first convert 16.0 pounds to grams (1 pound ≈ 453.592 grams). Then, calculate the number of moles of oxygen using the molar mass of oxygen (16.00 g/mol). Finally, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of oxygen atoms.
What is the molecular mass of O2?
The molecular mass of O2 (oxygen gas) is 32 g/mol. This is calculated by adding the atomic masses of the two oxygen atoms in the molecule (16 g/mol each).

HOW many grams pf ammonia are in 387x1021 molecules?
Assuming that this ammonia gas is at STP, you can use Avogadro's number to gind the number of moles of gas:(387 x 1021 molecules) x (1 mol / 6.02x1023particles) x (17.03 g / 1 mol) =110 g NH3
How would the determine the number of molecules in 3 mole of oxygen?
To determine the number of molecules of a substance, we can use Avogadro's number, which states that in every mole of a substance, there are 6.022 x 10^22 particles, or in this case molecules. This can be rewritten as the ratio: 1 mol / 6.022 x 10^22 molecules.This problem is deceptively tricky: you might think that given 3 moles oxygen, we can just write it as 3 mol O. However, it is important to note that oxygen naturally exists as O2. So, we have to convert what's given into moles of O3.00 mol O2 x 2 mol O = 6.00 mol O1 mol O2In this problem, we want to cancel out the mol unit in the numerator. We can flip the ratio above to make it 6.022 x 10^23 molecules/1 mol6.00 mol O x 6.022x10^22 molecules O = 3.61x10^22 molecules O1 mol O
