Final answer:
The mass of the gallium is 181.9 g.
Step-by-step explanation:
Gallium has a density of 2.70 g/cm³. Since we know the volume of the gallium is 67 cm³, we can calculate the mass using the formula: mass = density x volume. So, the mass of the gallium would be: 2.70 g/cm³ x 67 cm³ = 181.9 g.
