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.
3,7 moles of C8H11NO2 have 3,7 moles of oxygen (O2).
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
3.70 moles NaClO4 (4 moles O/1 mole NaClO4) = 14.8 moles oxygen
There are 6 moles of oxygen atoms in 2 moles of potassium dichromate (K2Cr2O7). Each mole of K2Cr2O7 contains 7 oxygen atoms, so 2 moles would contain 14 oxygen atoms. The molar mass of oxygen is 16 g/mol, so there would be 224 grams of oxygen in 2 moles of K2Cr2O7.
16 grams of oxygen how many moles is 0,5 moles.
3,7 moles of C8H11NO2 have 3,7 moles of oxygen (O2).
The nunber of moles of oxygen is 2,5.
The answer is 0,0095 moles.
23 moles of oxygen contain 138,509.10e23 molecules.
320 grams of oxygen is the equivalent of 10 moles.
The answer is 3,375 moles oxygen.
0,667 g oxygen equal 0,021 moles.
97,5 g of oxygen is equal to 5,416 moles.
There are twice as many oxygen atoms as carbon atoms in carbon dioxide, so 100.0 moles of carbon dioxide would contain 200.0 moles of oxygen atoms.
6,5 moles oxygen equals 208 g.
0,800 moles of oxygen (O2) is equivalent to 25,6 g.
