Question 7 of 22beginner🔧 ApplyNumerical2 marks

In a science lab, acid and water are mixed in the ratio of 1 : 5 to make a solution. In a bottle that has 240 mL of the solution, how much acid and water does the solution contain?

Correct Answer

Given: Ratio of acid : water = 1 : 5 Total solution = 240 mL

Formula: Total parts = 1 + 5 = 6 parts Acid = (1/6) × total solution Water = (5/6) × total solution

Calculation: Step 1: Total parts = 1 + 5 = 6 Step 2: Acid = (1/6) × 240 = 40 mL Step 3: Water = (5/6) × 240 = 200 mL Step 4: Verify: 40 + 200 = 240 mL and 40:200 = 1:5

Answer: The solution contains 40 mL of acid and 200 mL of water.

Explanation

The ratio 1:5 means there are 1+5=6 total parts. Acid is 1/6 of the total, water is 5/6 of the total.

Solution Steps

  1. Step 1: Total parts = 1 + 5 = 6

  2. Step 2: Acid = (1/6) × 240 = 40 mL

  3. Step 3: Water = (5/6) × 240 = 200 mL

  4. Step 4: Verify: 40 + 200 = 240 mL and 40:200 = 1:5
