Answer: Carlos Slim becomes the first Mexican and person from an emerging economy to top Forbes Richest Person list, with net worth of US$53.5 billion
There is one atom of sulfur :)
Metal is shiny, has a high electrical conductivity, a high thermal conductivity, and has a high density. Hope this helps.
Using the ideal gas law PV =nRTPV=nRT , we find that the pressure will be P =\frac{nRT}{V}P=
V
nRT
. Then, we'll substitute and find the pressure, using T = -25 °C = 248.15 K and R = 0.0821 \frac{atm\cdot L}{mol \cdot K}
mol⋅K
atm⋅L
:
P =\frac{nRT}{V} = \frac{(0.33\,\cancel{mol})(0.0821\frac{atm\cdot \cancel{L}}{\cancel{mol \cdot K}})(248.15\,\cancel{K})}{15.0\,\cancel{L}} = 0.4482\,atmP=

In conclusion, the pressure of this gas is P=0.4482 atm.
