1 mole O2 weighs 32 g
so 64 g O2 is 2 mol O2 gas
which has 2 X 6.022 X 1023 = 1.2066 X 1024 molecules of O2
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
To find the number of moles of oxygen in 0.16 g of oxygen gas, you first need to determine the molar mass of oxygen (O2), which is about 32 g/mol. Then, you can use the formula moles = mass / molar mass to calculate the number of moles. In this case, 0.16 g / 32 g/mol = 0.005 moles of oxygen gas.
I was wondering about this... but I think if you combined..The four oxygen gas O2, and the two of Hydrogen gas H2.. and predict was will happened I guess this is what it will or might be calculate, but Im not sure.KKKO2O2+H2H1O4+H2O2H
Since 1 mole is (6.022×1023 molecules)/(mol), so 9.02 x 1023 molecules would be 1.4978... mol
4.8/16 moles of oxygen atoms converts to 1.6/16 moles of ozone molecules.
To determine the number of molecules in 5.60 L of oxygen gas, we first need to convert the volume to moles using the ideal gas law. Then, we use Avogadro's number (6.022 x 10^23) to convert moles to molecules. The final answer will depend on the temperature and pressure of the oxygen gas.
4 moles of oxygen atoms are present in 4 moles of H2O
At STP, one mole of any gas occupies 22.4 liters. This is called molar volume. 113.97 liters ÷ (22.4 L/mol) = 5.09 moles Then convert moles to molecules (1 mole = 6.02 × 1023 molecules) 5.09 moles × (6.02 × 1023 molecules/mol) = 3.06 × 1024 molecules
Assuming you mean oxygen gas, the number of molecules can be found by first finding the number of moles = mass of oxygen (4g) / Molecular mass of oxygen gas (32 g mol-1) This tells us there is 0.125 mol of oxygen gas present. The number of molecules present is given by the number of moles x the avogadro constant (6.022x10^23) So the number of oxygen gas molecules present is equal to 0.125 x 6.022x10^23 = 7.5275x10^22 molecules
The answer is 0,173 moles.
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.
6,5 moles oxygen equals 208 g.
3,6 x 1023 molecules of oxygen gas O2 are equivalent to approx. 0,6 moles.
at stp 1 mole of a gas contains 22.4 litres. 9.1/22.4= .40625 moles o2. 1 mole of a gas contains 6.022E23 molecules so .40625 moles x 6.022E23 = 2.4464325E23 molecules, but you have to multiply by two due to it being diatomic, so answer x 2 = 4.892875E23 molecules
The equivalent in moles is 6,03.
The answer is 2 moles.
