Suppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read the base titrant volume as 2.49 mL. After running the titration and reaching the endpoint, you read the base titrant volume as 22.98 mL. What volume, in mL, of base was required for the titration?

The volume required for the titration is 20.49mL.

Explanation:

In a titration of an acid, you must fill the burette until a particular volume (In the problem, the burette is filled until 2.49mL).

Then, when the titration is ran, the final volume helps to find the volume required to the titration as follows:

Volume of titration = Final Volume - Initial volume

Volume of titration = 22.98mL - 2.49mL = 20.49mL

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
