I am doing a lab and I am not sure how to calculate the concentration of the chemical formulas used in the lab. Would I need to use the 15ml and add it to the 10 ml of the first solution to find the concentration. Thank you

Answers

Answer:

C = m/V

Explanation:

In order to calculate the concentration of a mixture you would need to use the formula for concentration, which is the following...

C = m/V

In this formula C is the concentration, m is the mass of the compound that is being added and mixed into the solution, and V is the total volume of the mixture. The mass of m is in terms of number of moles. Therefore, we would need more information in order to calculate the actual concentration of the mixture that you are trying to find in this scenario. Using the formula above should be enough using the values that you have in your actual workbook.

Answer:

a. "-ic"

For HCl, the name is Hydrochloric acid. As you can see, the suffix "-ine" of the element (originally chlorine) is changed to "-ic".

Following the same logic, the name for HBr is Hydrobromic acid; and the name for HI is Hydroiodic acid.
