12.00 moles of NaClO3 will produce how many grams of O2? 2 NaClO3 ---> 2 NaCl + 3 O2
How many grams of
We begin with a balanced chemical equation that is provided in the question.
Next we determine what we have and what we want.
We have 12.00 moles of
We set up a roadmap to solve the problem
We need the molar mass (
We need the mole ratio between
Now we set up conversion factors following the roadmap from above.
Unit we want in the numerator, unit to cancel in the denominator.
Multiply the numerators, and divide the denominators.
The outcome is
will be produced from 12.00 moles
I hope this was helpful.
The number of moles for NaClO3 = 12 moles
The number of moles for O2 = 18 moles
Molar mass of O2 = 32 g/mol
Final Answer (mass of O2) = PLEASE SEE BELOW!!!
If 2 moles of NaClO3 gives you 3 moles of O2,
it's because the mole ratio between NaClO3 : O2 is 2 : 3.
Then 12 moles of NaClO3 must give you [12 ÷ 2 then
You have found the number of moles (n) for O2.
Note that number of moles (n) = mass of substance (m)
The next step is to find out what is the molar mass (M) of O2.
If you look into your periodic table, the atomic weight is equivalent to the molar mass.
The molar mass of one O is = 16 g/mol.
Since there are two O present in the reaction (refer to equation), the molar mass of O2 is [16 g/mol
You've now found the molar mass (M).
The final step is to find out the mass (m) of O2. Since you found the number of moles (n) and molar mass (M), you can now find out the mass of substance.
Looking back at the formula
The mass of O2 is [18 moles
Overall, 12 moles of NaClO3 will produce 576 grams of O2.
