1 mole.
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
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.
0.515 moles
There are 2 moles of oxygen atoms in 35.2 g of oxygen. This is calculated by first finding the molar mass of oxygen (16 g/mol), then using the formula: moles = mass / molar mass.
The molar mass of oxygen is approximately 16 grams/mol. Therefore, the mass of 0.8 grams of oxygen is equivalent to 0.8/16 = 0.05 moles.
16 grams of oxygen how many moles is 0,5 moles.
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
4.8/16 moles of oxygen atoms converts to 1.6/16 moles of ozone molecules.
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
1 mole of oxygen weighs 16 grams. So, 1.8 moles would weigh 1.8 x 16 = 28.8g
Two moles of water are produced.
First determine the balanced chemical reaction:4Al + 3O2 ---> 2Al2O3Next figure out the number of moles of oxygen you start with by dividing 192 by the molecular weight of oxygen (16 g/mol). Then use the coefficients from the reaction to determine how many moles of Al would need to react with the oxygen to convert all the oxygen and aluminum to aluminum oxide.192 g * (1 mol O / 16 g O) * (4 moles of Al/6 moles of O) = 8 mol of AlFinally multiply by the molecular weight of Aluminum to figure out the mass:8 mol Al * (27 g/mol) = 216 g of Al
There are many different ways to calculate the moles and grams of oxygen. but one mole of oxygen is always gonna equal 32 grams because its diatomic, meaning it only comes in nature as O2. so it would be the atomic mass of oxygentimes 2. 16*2= 32
No. of moles = mass/relitive molecular mass in this case = 10/16 = 0.625 so that's 0.625 of a mole and a mole of anything contains 6.022 x 1023 atoms = 3.76 x 1023 atoms in 10g of oxygen.
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
First you need to work out the balanced equation. 2C2H2 + 5O2 -----> 4CO2 + 2H2O From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements). If 1 mole = 44g then 4 mole = 176g
A) 0.500 mol B) 1.000 mol C) 2.00 mol D) 3.00 mol E) 1/16 mol
