The number of moles of Al₂(SO₄)₃ is 1.2 mol
<u>Explanation:</u>
Given:
Volume of the solution, V = 501 mL
V = 0.501L
Molarity of the solution, M = 2.37M
Moles, n = ?
We know:
Molarity = 
On substituting the values we get:
Therefore, the number of moles of Al₂(SO₄)₃ is 1.2 mol
Answer:
Explanation:
remember that the phosphorous formula is P4
n P4 = mass / M.wt
825 / 4x 30.97 =
= 6.660 mole
Answer:
5.56g of FeCl2 can be produced
Explanation:
To solve this question we must find the moles of each reactant. With the moles and the chemical equation we can find limiting reactant. With limiting reactant we can find the moles of FeCl2 and its mass as follows:
<em>Moles HCl:</em>
1.5L * (0.25mol / L) = 0.375 moles HCl
<em>Moles Fe -Molar mass: 55.845g/mol-</em>
2.45g * (1mol / 55.845g) = 0.0439 moles Fe
For a complete reaction of 0.375 moles HCl are needed:
0.375 moles HCl * (1mol Fe / 2mol HCl) = 0.1875 moles Fe
As there are just 0.0439 moles Fe, <em>Fe is limiting reactant</em>
<em />
1mol of Fe produce 1 mole of FeCl2, 0.0439 moles Fe produce 0.0439 moles of FeCl2. The mass is:
<em>Mass FeCl2 -Molar mass: 126.751g/mol:</em>
0.0439 moles Fe * (126.751g / mol) =
<h3>5.56g of FeCl2 can be produced</h3>
The importance of Carbon is that it can clean, and its kind of bad for air though.
