Question

5 which element has a molar mass of 30.974 g/mol? * (0.5 points) palladium gallium phosphorus potassium

Explanation:

To determine which element has a molar mass of 30.974 g/mol, we recall the molar masses of the given elements:

• Palladium (Pd) has a molar mass around 106.42 g/mol.
• Gallium (Ga) has a molar mass around 69.723 g/mol.
• Phosphorus (P) has a molar mass of approximately 30.974 g/mol.
• Potassium (K) has a molar mass around 39.098 g/mol.

By comparing these values, we see that Phosphorus matches the given molar mass.

Answer:

C. Phosphorus
