Rubbing alcohol is 70% (m\/v) isopropyl alcohol by volume. How
many mL of isopropyl alcohol are in a 500 mL container<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n To calculate the volume of isopropyl alcohol in a 500 mL container of 70% (m\/v) isopropyl alcohol, we can use the given concentration. The “70% (m\/v)” means that there are 70 mL of isopropyl alcohol for every 100 mL of solution.<\/p>\n\n\n\n In a 500 mL container of 70% (m\/v) isopropyl alcohol, there are 350 mL of isopropyl alcohol<\/strong>.<\/p>\n\n\n\n The concentration of rubbing alcohol is often expressed as a percentage, which indicates how much of the active ingredient (in this case, isopropyl alcohol) is present per volume of the total solution. For rubbing alcohol labeled “70% (m\/v),” it means 70% of the solution is isopropyl alcohol, and the remaining 30% is water or another solvent.<\/p>\n\n\n\n To calculate the amount of isopropyl alcohol in a larger volume, such as a 500 mL container, you can use simple proportional math. Since 70% of any amount of solution is the volume of the isopropyl alcohol, you multiply the total volume (500 mL) by 0.70 (70%) to get 350 mL of isopropyl alcohol. This method is applicable to any solution where the concentration is given as a percentage.<\/p>\n","protected":false},"excerpt":{"rendered":" Rubbing alcohol is 70% (m\/v) isopropyl alcohol by volume.
