Answer:
The answer is Iron phosphide (Fe2P)
<span>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:
</span>(n/V) = P/RT = (745 torr)/(62.36 L-torr/mol•K)(337 K) = 0.0354 mol/L
Therefore the density will be:
<span>
Density = (352.02 g/mol)(0.0354 mol/L)/(1000 cm³/L) = 0.0125 g/cm³

B. It is not accelerating since equal and opposite forces cancel each other. Hope it helps
It's in the periodic table.
See the attached picture. The number below 'Zn' is the molar mass. The closest answer choice is 65.38
