If a recipe calls for two 10.5 oz cans of broth and 2 water you have 14oz how much should use if want to add because it might be too watery?

To find out how much broth you should add to the recipe, you need to calculate the total amount of liquid you have first. You have 2 cans of broth, each containing 10.5 oz, so that's 2 * 10.5 = 21 oz of broth. You also have 2 cups of water, or 2 * 8 = 16 oz of water. Adding these together, you have a total of 21 + 16 = 37 oz of liquid.

The recipe calls for a total of 2 cans of broth and 2 cups of water, which is 21 + 16 = 37 oz of liquid. Since you already have 37 oz of liquid, you don't need to add any more broth or water.

In summary, since you already have the amount of liquid required by the recipe, you don't need to add any more broth or water.
