Question

You have 200g or a solution that contains 30g of hydrochloric acid (HCI) what percent of your solution is made up of HCI acid?

Answer 1

Explanation:

Percent by mass of HCl is 15 %.

(mass of solute÷mass of solution)×100

(30÷200)×100

=15%

Answer 2

Required Answer:-

Given :

• Mass of HCl = 30 g
• Mass of solution = 200 g

To Find :

Percentage of HCl acid in the solution.

Solution :

❒ Mass by mass percentage concentration of solution is defined as the amount of solute in grams dissolved present 100 grams of solution$.$

Then,

• m = mass of solute
• M = mass of solution

⇛ m/M % = m of solute / M of solution × 100

⇛ m/M % = 30 g / 200 g × 100

⇛ m/M % = 30 / 2 %

⇛ m/M % = 15 %

Hence:-

The HCl makes 15 % of the total dilute acid solution.
