Answer:
the percentage of your solution that made up of HCI acid is 15%
Explanation:
The computation of the percentage of your solution that made up of HCI acid is given below:
Given that
There is 200g or a solution that have 0 g of hydrochloric acid (HCI)
Based on the above information
The percentage is
= 30g ÷ 200g
= 15%
Hence, the percentage of your solution that made up of HCI acid is 15%
