It depends on the weight, it usually runs around $20-$25 a Gram. Depending on current prices.
The 14k means it is gold and the kb is the maker or company.
The b in 14 KB is where the gold came from in your case it is from Mexico.
She's hot
It's real gold,It just means that it was made in Mexico. Yes sir!
One thousand KB's = 1MB. So it'd be 14000 KB's.
To find the Kb for the conjugate base, you can use the relationship Kw = Ka * Kb. Rearrange the equation to solve for Kb: Kb = Kw / Ka. Plugging in the values, you get Kb = (1.0 x 10^-14) / (3.1 x 10^-10) = 3.23 x 10^-5.
If you 1 oz gold from Apmex, in ok., you pay approx $187.00 tax KB.
Since Kw = Ka * Kb, we can rearrange the equation as Kb = Kw / Ka. Plugging in the values, Kb = (1.0 x 10^-14) / (2.5 x 10^-4) = 4.0 x 10^-11. This is the Kb for the conjugate base of the given acid.
To find the Kb of the conjugate base, use the relationship Kw = Ka x Kb. Rearrange the equation for Kb: Kb = Kw / Ka = (1.0 x 10^-14) / (2.5 x 10^-4) = 4.0 x 10^-11.
The 14 on gold jewelry means that is made of 14 karat (or 14 kt) gold.
To find the Kb of the conjugate base, you can use the relationship Kw = Ka * Kb. At 25°C, the value of Kw is 1.0 x 10^-14. Given Ka = 3.1 x 10^-10, you can solve for Kb using Kb = Kw / Ka. This gives you Kb = 1.0 x 10^-14 / 3.1 x 10^-10 = 3.23 x 10^-5.
To determine the pH using the dissociation constant (Kb) of a weak base, you can use the equation: pOH -log(Kb) and then calculate the pH by subtracting the pOH value from 14.
