 Okay, so if the density of mercury is 13.6 grams per mil, what's the specific gravity of mercury? Let's figure that out. Okay? So what did we say the density of water was at 4 degrees Celsius? 1.00. What? Oh, I'm sorry. I can't hear you guys. Mililies, right? Okay. So how do we do specific gravity? I'm going to help me. The density of the object over the density. Yeah. So the density of the object over the density. Yeah. So the density of the object over the density of water at 4 degrees Celsius, right? So the density of our object is mercury, right? And that's 13.6, and what I put in my units, right? Grams per mil and divided it by what? 1.00 grams per mil. So what's my answer? 13.6, okay? So I just went over for about 20 minutes how never you're going to have numbers without units except for very rare occasions. This is one of those rare occasions, okay? So specific gravity, you would not put units, okay? So that's one of them that you don't. And it's just for ease of, you know, conveying information, okay? So you know you're talking about specific gravity, so you just say it's 13.6 or 4.9 or something, okay? So just remember it's always divided by that, 1.00 grams per mil. So because effectively what we're doing is just getting rid of the units. That's what we want to do in this particular situation. Any questions? Can I kill it? Okay.
