Based on the Ksp calculations, the molar solubility of AgCl in 0.500 M of NH₃ is equal to 2.77 × 10⁻² M.

<h3>How to determine the molar solubility.</h3>

First of al, we would write the properly balanced chemical equation for this chemical reaction:

                  AgCl(s) ⇆ Ag⁺(aq)+ Cl⁻(aq)       Ksp = 1.8 × 10⁻¹⁰

               

               AgCl(s) + 2NH₃(aq) ⇆ Ag(NH₃)₂⁺(aq)   Kf = 1. 7 × 10⁷

<u>Given the following data:</u>

  • Ksp of AgCl = 1.8 × 10⁻¹⁰
  • Concentration of NH₃ = 0.500
  • Kf of ag(nh₃)₂⁺ = 1.7 × 10⁷

K = Ksp × Kf

K = 1. 80 × 10⁻¹⁰ × 1.7 × 10⁷

K = 3.06 × 10⁻³

Mathematically, the Ksp for the above chemical reaction is given by:

K=\frac{ [Ag(NH_3)_2^{+}][Cl]}{[NH_3]^2}\\\\3.06 \times 10^{-3}=\frac{[x][x]}{0.50^{2 }}\\\\3.06 \times 10^{-3}=\frac{x^2}{0.25}\\\\x^2 = 7.65\times 10^{-4}\\\\x=\sqrt{7.65\times 10^{-4}}

x = 2.77 × 10⁻² M.

At a large corporation, the distribution of years of employment for the employees has mean 20.6 years and standard deviation 5.3
Cerrena [4.2K]

Answer:

Yes

Explanation:

The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

z=\frac{x-\mu}{\sigma}\\\\where\  \mu=mean.\sigma=standard\ deviation,  x=raw\ score.\\\\For\ a \ sample\ size\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }

For a normal distribution with a mean of μ and standard deviation σ, For any sample size (n) drawn from this population, the sample mean is normally distributed, with mean \mu_x=\mu and standard deviation \sigma_x=\frac{\sigma}{\sqrt{n } } \\\\.

Hence given that a mean of μ = 20.6 years and standard deviation σ = 5.3 years, for a sample size of 100:

mean \mu_x=\mu=20.6\ years and standard deviation \sigma_x=\frac{\sigma}{\sqrt{n } } =\frac{5.3}{\sqrt{100} }=0.53\ years \\\\.
