You cannot use baking powder as a substitute for baking soda.
160 table spoons
About 1.5 teaspoons. If the recipe calls for self raising flour and you don't have any then add 1.5 teaspoons of baking powder and 0.5 teaspoons of salt.
Generally you use 1 to 2 teaspoons of baking powder to each cup of flour.
There are two tablespoons in an ounce, and three teaspoons in a tablespoon, so six teaspoons in an ounce. $0.99 / 6 teaspoons = $0.165 per teaspoon So about $0.17.

One to one and a half teaspoons of baking powder and a pinc to one half teaspoon of salt to a cup (125 g) of flour.
First of all, you can not buy just 2 teaspoons of baking powder. You would need to buy a package.The price depends on where you buy the baking powder and on the size of package you purchase.In the US, one teaspoon equals about 1/6 of an ounce. Two teaspoons would be 1/3 of an ounce.Looking at various websites, the price of one ounce of baking powder costs between $0.30 and more than $1.00. Taking the $0.30 per ounce, two teaspoons would cost about $0.10. Taking $0.99 per ounce, two teaspoons would cost about $0.33.
For one cup of self-rising flour I use 1 cup all-purpose flour, and add: 1 1/4 teaspoons baking powder AND 1/8 teaspoons salt
I don't know how much volume 4 oz. will be, but most recipes use the ratio of 1 teaspoon of baking powder to 1 cup of flour. Weigh the flour, measure it and find the amount of baking powder that way.
the purpose of baking powder in a cake is to make it rise and not make it flat and if you put too much of baking powder your cake might burst in the oven/microwave what ever you use
around 3 teaspoons, but this will vary according to the recipe.

Baking powder is a mixure of powdered baking soda and the powder, 'Cream of Tartar' with a bit of cornstarch to keep the mixture from clumping.
