Answer:
2.10 g
Explanation:
Write the unbalanced reaction:
Fe + O₂ → Fe₂O₃
Balance it:
4Fe + 3O₂ → 2Fe₂O₃
Now use stoichiometry. Convert mass of Fe to moles of Fe:
1.47 g Fe × (1 mol Fe / 55.8 g Fe) = 0.0263 mol Fe
Convert moles of Fe to moles of Fe₂O₃:
0.0263 mol Fe × (2 mol Fe₂O₃ / 4 mol Fe) = 0.0132 mol Fe₂O₃
Finally, convert moles of Fe₂O₃ to mass of Fe₂O₃:
0.0132 mol Fe₂O₃ × (159.7 g Fe₂O₃ / mol Fe₂O₃) = 2.10 g Fe₂O₃
Answer:
the cycle of water and how it evaporates with energy from the sun and the droplets are stored in clouds which is condensation and when it rains or snows those are forms of precipitation
Explanation:
12.34 is the answer I think
The mass of 2.28 mol of SO₃ is 182.4 g.
<h3>What is mass?</h3>
Mass can be defined as the quantity of matter a body contains.
The S.I unit of mass is kilogram (kg). other units of mass include grams (g), milligram (mg), microgram (μg) etc.
<h3>What is a matter?</h3>
A matter is anything that has mass and occupies space. Matter exist in three states.
- Solid state
- Liquid state
- Gaseous state
To calculate the mass of 2.28 mol of SO₃, we use the formula below.
Formula:
- m = nM............. Equation 1
⇒ Where:
- m = mass of SO₃
- n = number of mole of SO₃
- M = molar mass of SO₃
From the question,
Given:
Substitute these values into equation 1
Hence, the mass of 2.28 mol of SO₃ is 182.4 g.

This is a hypothesis question. This is an educated guess, basically. In my opinion, I think the tails side would hold more water.
