🤓 Based on our data, we think this question is relevant for Professor Cole's class at IOWA.
Recall that a Face-Centered Cubic (FCC) unit cell has 4 atoms per unit cell.
Formula for density:
Edge length (a) = 383.3 pm
Molar mass of Iridium (Ir) = 192.2 g/mol (refer to the periodic table)
Iridium (Ir) has a face-centered cubic unit cell with an edge length of 383.3 pm. Calculate the density of solid iridium.
