Question: In a mixture of 50 liters, the ratio of two chemicals is 4:1. How many liters of the first chemical are there?

Options:

Correct Answer: 40 liters

Solution:

Total parts = 4 + 1 = 5. Volume of the first chemical = (4/5) * 50 = 40 liters.

In a mixture of 50 liters, the ratio of two chemicals is 4:1. How many liters of the first chemical are there?

Step 1: Understand that the total mixture is 50 liters.
Step 2: Identify the ratio of the two chemicals, which is 4:1.
Step 3: Add the parts of the ratio together: 4 (for the first chemical) + 1 (for the second chemical) = 5 parts total.
Step 4: Find out how much one part is worth by dividing the total volume by the total parts: 50 liters / 5 parts = 10 liters per part.
Step 5: Calculate the volume of the first chemical by multiplying its parts by the value of one part: 4 parts * 10 liters per part = 40 liters.
