Volume of Fe(NO₃)₃ = 5.00 ml
Total voluem of the solution = 20.0 ml
Concentration of Fe(NO₃)₃ = 0.002 M
Assuming complete dissociation of Fe(NO₃)₃ concentration of Fe³⁺ = 0.200 M
Using the dilution equation, M₁V₁ = M₂V₂
where M₁ and M₂ are the initial and final concentration of Fe³⁺ respectively and V₁ and V₂ are the initial and final volume of Fe³⁺ respectively
Plugging the data we get,
M₂ = 
= 5 x 10⁻⁴
Therefore, the concentration of Fe³⁺ once diluted in the mixture is 5 x 10⁻⁴M
Answer:
The electron configuration for calcium is: 1s2 2s2 2p6 3s2 3p6 4s2. Since calcium is in the fourth row and the second column of the s-block on the periodic table of elements, its electron configuration ends in 4s2. Every lower orbital is filled, starting with the 1s orbital.

a minute planet; a body that could or did come together with many others under gravitation to form a planet. Planetesimals are small rock fragments that combined together to eventually form planets
Answer:
λ = 1.1×10⁸ m
Explanation:
Given data:
Frequency of wave = 2.7 Hz
Wavelength of wave = ?
Solution:
Formula:
Speed of wave = frequency × wavelength
Speed of wave = 3×10⁸ m/s
now we will put the values in formula.
3×10⁸ m/s = 2.7 s⁻¹ × λ
λ = 3×10⁸ m/s /2.7 s⁻¹
λ = 1.1×10⁸ m
Answer:
P(total pressure) = 504 mmHg = 504mm/760mm/atm = 0.663 atm
Explanation:
Apply Dalton's Law of Partial Pressures.
P(total) = ∑Partial Pressures = ∑(256mm + 198mm + 48mm) = 504 mmHg
P(total pressure) = 504 mmHg = 504mm/760mm/atm = 0.663 atm
