What is the density of Iodine gas at 2.36 atm and 65.0 C?
timurjin [86]

The density : 21.63 g/L

<h3>Further explanation</h3>

The gas equation can be written  

\large {\boxed {\bold {PV = nRT}}}

where  

P = pressure, atm  

V = volume, liter  

n = number of moles  

R = gas constant = 0.08206 L.atm / mol K  

T = temperature, Kelvin  

T = 65+273=338 K

P=2.36 atm

MW Iodine gas (I₂)=254

The density :

\tt \rho=\dfrac{P\times MW}{RT}\\\\\rho=\dfrac{2.36\times 254}{0.082\times 338}=21.63~g/L

What is the molarity of NaOH, if 15g of NaOH is mixed with 600mL?
inn [45]
M(NaOH)=15 g

v=600 ml=0.6 l

n(NaOH)=m(NaOH)/M(NaOH)

C=n(NaOH)/v=m(NaOH)/[M(NaOH)v]

C=15g/[40g/mol*0.6 l]=0.625 mol/l

0.625M



[H⁺]=7.5*10⁻²
pOH=14-pH=14+lg[H⁺]
pOH=14+lg(7.5*10⁻²)=14-1.125=12.875
