W/v
Okay, kiddo. So, w/v is a way to measure how much of something is dissolved in a liquid. Let's say you have a glass of water, and you want to know how much sugar you've added to it. You might use w/v to figure that out.
"W" stands for weight, which means how heavy something is. "V" stands for volume, which means how much space something takes up. By using w/v, we can figure out how much sugar (or whatever) is in the water by measuring how heavy it is compared to how much space it takes up.
So, if we put 10 grams of sugar into a glass of water that's 100 milliliters (that's a fancy word for "same as cubic centimeters"), we would say that the w/v of sugar in the water is 10 grams per 100 milliliters (or 10 g/100 mL for short). That tells us how much sugar is in the water, even though we can't see it because it's dissolved.
It's kind of like when you put a spoonful of hot cocoa mix into your milk. You stir it up and the mix disappears, but you can still taste it because it's dissolved. By using w/v, we can measure how much cocoa mix (or sugar, or whatever) we've added to our milk.
Does that help, kiddo?
