What would be the number of phosphorus atoms in a 2.34 g sample of calcium phosphate?
(My answer was 9.1*10^21 but I'm not sure if I went wrong somewhere in the process)
Answer: You were right I'm not sure why it says you're incorrect?
Explanation:
The number of phosphorus atoms in a 2.34 g sample of calcium phosphate is calculated via molar mass and Avogadro's number. Your estimate of 9.1 x 10^21 phosphorus atoms is very close to the actual atoms present.
Explanation:To solve this inquiry, let's start by finding the molar mass of calcium phosphate (Ca3(PO4)2). The molar mass is calculated as follows: 3(40.08 g/mole for Ca) + 2(1.01 g/mole for H) + 2(15.999 g/mole for O) + 2(30.974 g/mole for P) = 310.18 g/mole.
Next, divide the mass of the sample by the molar mass of calcium phosphate to find number of moles: 2.34 g ÷ 310.18 g/mole = 0.00754 moles.
Remember that 1 mole of calcium phosphate contains 2 moles of phosphorus atoms. Therefore, the number of moles of phosphorus atoms is 2*0.00754 = 0.01508 moles.
Then, use Avogadro's number (6.02 x 1023 atoms/mole) to find the number of phosphorus atoms: 0.01508 moles * 6.02 x 1023 atoms/mole = 9.08 x 1021 atoms. Your estimate of 9.1 x 1021 phosphorus atoms is essentially correct!

how many grams of aluminum bromide are formed from the reaction of aluminum and hydrogen bromide if you have excess al and 121 g of hbr
The reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.
The chemical equation for the reaction between aluminum and hydrogen bromide is:
[tex]2 Al + 3 HBr[/tex] →[tex]Al_2Br_6[/tex]
From this equation, we can see that the reaction is a stoichiometric reaction, which means that the ratio of the reactants and products is fixed and is determined by the coefficients in the balanced equation.
If we have 121 grams of hydrogen bromide, the number of moles of hydrogen bromide can be calculated using the molar mass of hydrogen bromide ([tex]HBr[/tex]) which is approximately 80.9 g/mol. So:
121 g [tex]HBr[/tex] / 80.9 g/mol = 1.49 mol [tex]HBr[/tex]
Since the coefficient of hydrogen bromide in the balanced equation is 3, we know that for every one mole of aluminum, we need 3 moles of HBr. So, in this case, we have excess [tex]Al[/tex], which means the limiting reactant is [tex]HBr[/tex], and we have 1.49 moles of [tex]HBr[/tex].
The number of moles of aluminum bromide ([tex]Al_2Br_6[/tex]) formed can be calculated by dividing the number of moles of [tex]HBr[/tex] by the coefficient of [tex]HBr[/tex] in the balanced equation, which is 3
1.49 moles [tex]HBr[/tex] / 3 = 0.497 moles [tex]Al_2Br_6[/tex]
We can calculate the number of grams of aluminum bromide by multiplying the number of moles by the molar mass of aluminum bromide, which is approximately 427.3 g/mol
0.497 moles [tex]Al_2Br_6[/tex] * 427.3 g/mol = 212.44 g [tex]Al_2Br_6[/tex]
So, the reaction of aluminum and hydrogen bromide will form 212.44 grams of aluminum bromide.

When sodium is heated, a yellow spectral
line whose energy is 3.37 x 10-19 j per photon is
produced
what is the frequency of this light?
explain please
Sodium is heated, a yellow spectral line whose energy is 3.37 x 10-19 j per photon is produced. The frequency of this light is 5.08 x 10^14 Hz
The frequency of light can be calculated using the equation: frequency (ν) = energy (E) / Planck's constant (h).
In this case, the energy of the photon is given as 3.37 x 10^-19 Joules, and Planck's constant is approximately 6.63 x 10^-34 Joules seconds.
So the frequency of this light would be:
ν = E / h
= (3.37 x 10^-19 Joules) / (6.63 x 10^-34 Joules seconds)
= 5.08 x 10^14 Hz
This is a very high frequency, which corresponds to a very short wavelength, in the ultraviolet range of the electromagnetic spectrum.
