4.50 moles NO2 X (46 grams NO2) / (1 mole NO2) x (4 moles NO2) / (7 moles O2) x (1 mole O2) / (32 gm O2) = 3.70 grams O2
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
The balanced equation for the reaction is 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O. This shows that 13 moles of diatomic oxygen are required to burn 2 moles of butane. By proportionality, (4.8/2)13 or 31.2 moles of oxygen are required to burn 4.8 moles of butane. This corresponds to 31.2(32) or 1.0 X 103 grams of oxygen.
There is no direct relationship between grams of oxygenand atoms of oxygen. Use the atomic mass to convert grams to moles and Avogadro's number to convert moles to atoms.Since you are converting from grams O, this goes in the denominator (on the bottom) of the first factor. You want to end up in units of atoms of O, so this goes in the numerator (on the top) of the last factor.g O1.00 mole O6.02E+23 atom O= atoms O16.0 gram O1.00 mole ONote that the units grams oxygen "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are atoms oxygen.
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
Multiply the molar mass value ( 32.0 grams per mole O2) by the number of moles (1.5 mole) to get its mass (48.0 grams for 1.5 mole O2)
800 g oxygen are needed.
16 grams of oxygen how many moles is 0,5 moles.
320 grams of oxygen is the equivalent of 10 moles.
12.8 grams oxygen (1 mole O/16.0 grams) = 0.800 moles of oxygen
0,667 g oxygen equal 0,021 moles.
The answer is 224,141 grams oxygen.
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.
0,800 moles of oxygen (O2) is equivalent to 25,6 g.
6,5 moles oxygen equals 208 g.
The number of moles in exactly 64 grams of oxygen (O2) is two.
4.80 grams O2 (1 mole O2/32 grams ) = 0.150 moles of O2
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
