Answer on Question #54763 – Chemistry – Other

Question:

F2(g) in grams per cubic centimeter if at 0 celcius 1 mole of it occupies 22.4L

Answer:

The mass of 1 mole fluorine is determined by the equation:

$$m = vM$$

, where $v$ – the number of moles and $M$ – the molecular weight which equals $19 + 19 = 38 \, \text{g/mol}$$

Thus, $m = 1 \, \text{mole} \times 38 \, \text{g/mol} = 38 \, \text{g}$

If $1 \, \text{ml} = 1 \, \text{cm}^3$ then the mass per cubic centimeter is:

$$d = m/V$$

, where $V$ – the volume in ml

$$d = 38 \, \text{g} / 22400 \, \text{ml} = 1.696 \times 10^{-3} \, \text{g/ml} = 1.696 \times 10^{-3} \, \text{g/cm}^3$$
