Final answer:
To calculate the density of solid crystalline vanadium, you can use the formula for the density of a body-centered cubic (BCC) structure. By substituting the values into the formula, you can find the density of vanadium.
Step-by-step explanation:
The density of a solid can be calculated by dividing its mass by its volume. In the case of a body-centered cubic (BCC) unit cell, there are two atoms in each unit cell. The formula for the density of a BCC structure is:
Density = (2 * molar mass) / (a^3 * Avogadro's number)
Given that the radius of a vanadium atom is 134 pm, we can calculate its molar mass and substitute the values into the formula to find the density.
