volume per volume is a unitless quantity lol. It's the same number...anything divided by itself is 1. It's just mL still because the unit from the 3000mL is still there. You don't need to introduce more units to make that work. It's already fine.
Hi, when the ratio compares two different components, then it is NOT unitless. Here we have 0.4 ml of alcohol per 1 ml of medium. Hence, the units cannot cancel even if they are both measured in ml. Nevertheless, you can simply get away with the calculation without knowing all those microdetails
Thanks alot,, may Allah protect and bless you,,, 🇮🇶👏🏻
