So let's do another one of these density of the liquid problems, but this time we won't do an unknown liquid We'll do probably the most dense liquid that you'll actually see in undergraduate chemistry. So the problem says calculate the mass in grams of 10.0 milliliters of mercury if the density of mercury is 13.6 grams per mil. So very dense liquid 13.6 grams per mil. And it says that the volume we've got is the same grams. So we're lucky. So that one's pretty easy because remember this is the same. This cancels out our units. So divided by one mil because we want grams on the top because grams is the mass number 10.0 mils. To cancel out, I'm just going to move that over. Both of these have 36 pigs. So 136 grams per 10 mils of mercury. Dense liquid I guess I should say. Heavy if you got a lot of it. Just like anything.


So then there are games like Shadowgate.   Bellowing like a fool, you leap off the bridge and into the blaze. Death.  You can't even scream because you no longer have a throat, let alone a larynx. I suspect Nintendo of America didn't read all the text in this rhyme. So this game, Shadowgate, is famous for its death. But not just because there's a bunch of deaths, because the deaths are all interesting and weird, and the game is encouraging you to explore these deaths.  If you keep using the torch on yourself, eventually this happens and you die. So the game decided, what if this guy tries to set himself on fire? Let's warn him away a few times and then let's set him on fire. So what we're doing here is we're now exploring the narrative of failure. Now we're getting into an interesting place. Now this game, it still has a narrative to the end.  But every time Mario falls in the pit, it's a different thing. It's interesting, we can explore it, and a lot of games have done this, even if you didn't realize it.
