uranium hexafluoride is a solid at room temperature, but it boils at $56^o C$.determine the density of uranium hexafluoride at

PSYCHO15rus [73]

If it is known that at 60 °C and 745 torr UF₆ is present only as a gas then we can make the assumption that:

(n/V) = P/RT = (745 torr)/(62.36 L-torr/mol•K)(337 K) = 0.0354 mol/L
Therefore the density will be:

Density = (352.02 g/mol)(0.0354 mol/L)/(1000 cm³/L) = 0.0125 g/cm³

The question is incomplete, the complete question is :

Calculate the approximate number of atoms in a bacterium. Assume the average mass of an atom in the bacterium is 10 times the mass of a hydrogen atom.(Hint the mass of hydrogen atom is on order of $10^{-27}$ kg and the mass of bacterium is on order of $10^{-15}$ kg
