# What is the density of a fictional gas that has a gram molecular mass of 10.57 g?

Mar 4, 2016

$\rho$ $=$ $\text{Mass"/"Volume}$

#### Explanation:

We assume that the gas behaves ideally, and, therefore, under standard conditions ($298$ $K$, $1$ $a t m$), $1$ $m o l$ will occupy $25.4$ ${\mathrm{dm}}^{3}$

$\rho$ $=$ $\frac{10.57 \cdot g}{25.4 \cdot {\mathrm{dm}}^{-} 3}$ $=$ ?? $g \cdot {\mathrm{dm}}^{-} 3$

Note $1 \cdot {\mathrm{dm}}^{-} 3 = 1 L$

I am not sure I like this question, because I cannot think of an actual gas that would display these properties.
