Standard pressure is 101.3 kpa, which is equal to 760.o mmhg. if gas has a pressure of 545 mmhg, what is its pressure in kpa to the proper number of significant figures?

72.6 kPa

Explanation:

We can use ratios to answer this question

760 mmHg : 101.3 kPa

545 mmHg : x

then we cross multiply keeping note of the unit

760x mmHg = 55 208.5 mmHg.kPa

x = 72.6 kPa

*It is worth noting that the k that represents kilo in kPa must be a small letter all the time

to be fair, you have to have a very high iq to understand rick and morty. the humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. there's also rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from narodnaya volya literature, for instance. the fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about life. as a consequence people who dislike rick & morty truly are idiots- of course they wouldn't appreciate, for instance, the humour in rick's existential catchphrase "wubba lubba dub dub," which itself is a cryptic reference to turgenev's russian epic fathers and sons. i'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as dan harmon's genius wit unfolds itself on their television screens. what fools.. how i pity them.

and yes, by the way, i do have a rick & morty tattoo. and no, you cannot see it. it's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 iq points of my own (preferably lower) beforehand. nothin personnel kid

the answer is definitely c.
