Group Title
uranium hexafluoride is a solid at room temperature, but it boils at \(56^o C\).determine the density of uranium hexafluoride at \(60^o C\) and 745 torr.
i know d = m/v and PV = nRT
but how can i use them here? or do i even use them here?

you can solve for n and get the mass using the periodic table and then you can solve for v

Use the other formula to find them ^_^

if i remember right 760 torr = 1 atm...torr is a unit of measurement for pressure

p=745 torr v=? n=? R=? T=6056 (i think) d=? (looking for) m=? v=?

do you know \[p =\rho \times r \times T \div M\] where rho is density and M is molecular mass
 2 years ago

SUROJ Group TitleBest ResponseYou've already chosen the best response.2
P is pressure

SUROJ Group TitleBest ResponseYou've already chosen the best response.2
since n= m/M , you can get m/V = rho

uhhh could you rewrite that equation you wrote? kinda vague... \[\huge P = \frac{\rho RT}{M}\]

is that right?

oh i see now

so \[\frac{PM}{RT} = \rho\] right? R = 0.0821

so which T am i going to use?

NotTim Group TitleBest ResponseYou've already chosen the best response.0
probably, because that's the one that applies to this situation

hmm then i need to convert torr into atm and C into K right
 2 years ago

SUROJ Group TitleBest ResponseYou've already chosen the best response.2
yup and 1 torr = 1 atm

i thought it was 760 torr = 1 atm o.O

i got the answer as 126.76 g/L is that right?

zbay Group TitleBest ResponseYou've already chosen the best response.1
set n to 1 and solve for V then you take the molar mass of the molecule you are looking at and calculate your density

R is a constant.
