Final answer:
The density of fcc palladium is approximately 11.98 g/cm³, which is close to the accepted value of 12.023 g/cm³. Hence, it is likely true but may vary slightly based on the precision required.
Step-by-step explanation:
The density of face-centered cubic (fcc) palladium is reported to be 11.98 g/cm³. The inquiry to confirm whether this statement is true or false requires knowing the actual density of palladium. Based on recorded values, the density of fcc palladium is generally accepted to be around 12.023 g/cm³. Therefore, the provided density of 11.98 g/cm³ could be considered approximately true but might be slightly inaccurate depending on the level of precision required. For example, in a scientific context where exact values are essential, this slight deviation could be significant.
However, in an educational setting, such as a high school chemistry class, this slight variation is generally acceptable and the statement can be considered to be true within a reasonable margin of error.
