Answer:
292.4 g
Explanation:
- 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
First we <u>convert 53.7 g of Al into moles</u>, using its<em> molar mass</em>:
- 53.7 g ÷ 27 g/mol = 1.99 mol Al
Then we <u>convert Al moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.99 mol Al * = 2.98 mol H₂SO₄
Finally we <u>convert 2.98 moles of sulfuric acid into gram</u>s, using its <em>molar mass:</em>
- 2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
Answer:
Explanation:
Hello,
In this case, for the given balanced chemical reaction:
Thus, since hydrogen and hydrogen iodide are in a 1:2 mole ratio, we can easily compute the yielded volume as shown below:
Thus, is possible, due to the Avogadro's law which allows to relate moles and volume by a directly proportional relationship.
Regards.
It should be 40.08 grams...because the atomic mass is equivalent to 1 mole of atoms of an element in grams, and 6.023 × 10^23 atoms of calcium is the same as 1 mole of calcium.
Hope this helps!
Answer:
<u>390g</u>
Explanation:
it's moles actually...
Molar mas of CaF2 is =78g/mol
It means 78g per mole...Si If you have 5 moles..that means you have...
78*5g of CaF2...
This chemical reaction should follow the Law of Conservation of Mass where mass cannot be created nor destroyed. That is, what goes in a system should be equal with what goes out the system. For this problem, the mass of C that is produced assuming there are no by-products should be 600 pounds.
