Q
Q: A solution contains 25% alcohol. If 200 ml of the solution is taken, how much alcohol is present in it?
Solution:
25% of 200 ml = 0.25 * 200 = 50 ml of alcohol.
Steps: 7
Show Steps
Step 1: Understand that 25% means 25 out of every 100 parts.
Step 2: We have a total of 200 ml of solution.
Step 3: To find out how much alcohol is in 200 ml, we need to calculate 25% of 200 ml.
Step 4: Convert 25% to a decimal. 25% as a decimal is 0.25.
Step 5: Multiply the decimal (0.25) by the total volume (200 ml).
Step 6: Calculate 0.25 * 200 = 50 ml.
Step 7: Therefore, there are 50 ml of alcohol in the 200 ml solution.
