Answer:
<em>23.9 grams carbon</em>
Explanation:
One mole of carbon is 6.023 x 10^23 atoms of C.
If we calculate moles, we can use the molar mass of carbon (12 g/mole) to determine mass of 12x10^23 atoms of C.
(12x10^23 atoms of C)/(6.023 x 10^23 atoms of C/mole C)
moles C = 1.992 moles C
(1.992 moles C)*(12 g/mole C) = 23.9 grams carbon
Answer: Theoretical yield of produced by 8.96 g of S is 33.6 g
Explanation:
To calculate the moles :
The balanced chemical equation is:
According to stoichiometry :
2 moles of produce = 3 moles of
Thus 0.28 moles of will produce= of
Mass of
Thus theoretical yield of produced by 8.96 g of S is 33.6 g
The answer is physical or chemical change
