Find the Density at STP V

$V$

Step 1

To find the mass of $1$ mole of $V$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $V$ $=$ $(mass of V)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $V$ $=$ $(50.93999862)$

Step 3

Remove parentheses.

mass of $1$ mole of $V = 50.93999862 g$

Step 4

One mole of any gas occupies $22.4 L$ at STP (standard temperature and pressure).

$V = 22.4 L$

Step 5

Density is mass over volume.

$\frac{50.93999862 g}{22.4 L}$

Step 6

Factor $50.93999862$ out of $50.93999862 g$ .

$\frac{50.93999862 (g)}{22.4 L}$

Step 7

Factor $22.4$ out of $22.4 L$ .

$\frac{50.93999862 (g)}{22.4 (L)}$

Step 8

Separate fractions.

$\frac{50.93999862}{22.4} \cdot \frac{g}{L}$

Step 9

Divide $50.93999862$ by $22.4$ .

$2.27410708 \frac{g}{L}$

Step 10

Combine $2.27410708$ and $\frac{g}{L}$ .

$\frac{2.27410708 g}{L}$
