100-175 USD or so
The value of a Mossberg 351-KA, a .22 caliber semi-automatic rifle, typically ranges from $200 to $400, depending on its condition, age, and any modifications. Factors such as original packaging, included accessories, and overall demand in the market can also influence its worth. For the most accurate valuation, it's advisable to consult recent sales data or a firearms appraisal expert.
In good condition about $5000 dollars.
That model was made from 1960-1971. If yours has no serial number, it was made prior to the 1968 Gun Control Act. Value will depend on condition, but about $125-150 for one in Very Good condition. Nice rifles.
I was just offered on in good condition for $100. I see them offered for sale on line in the $100 to $200 range. This is for average run of the mill guns in good and better condition. Obviously condition and rarity are the determining factors.
1960 through 1968.
1960-1968, supposedly.
Anywhere from $50.00 to about $150.00 I saw one on a site today. It was listed for $225.00, but I think he's reaching. Those shotguns sold for a bit under $50.00 brand new back in the '50's. It was my very first gun. I traded it about 30 years ago, and I wish I didn't. Strictly sentimental value for me.
The Ka value of ammonium (NH4+) is 5.6 x 10^-10.
These were made from 1968-1983.
ka= 1.62 x 10^-12
The Ka value of nitric acid (HNO3) is approximately 25 × 10^6.
The relationship between Ka and Kb values is that they are related by the equation Kw Ka Kb, where Kw is the ion product of water. If you know the Kb value, you can determine the Ka value by rearranging the equation to solve for Ka.
