Final answer:
The density of the metal coin, which has a mass of 7g and a volume of 1.43 cm³, is calculated using the formula Density = Mass / Volume and is approximately 4.8951 g/cm³.
Step-by-step explanation:
To calculate the density of the coin, we need its mass and volume. The mass of the coin is given as 7g. The volume of the coin is also provided as 1.43 cm³. Density is defined as mass per unit volume, which can be calculated using the formula:
Density = Mass / Volume
In this case, the density of the coin would be calculated as follows:
Density = 7g / 1.43 cm³ = 4.8951 g/cm³ (rounded to four decimal places)
This means that the density of the metal coin is approximately 4.8951 g/cm³, indicating that the coin is denser than water (since water has a density of 1 g/cm³).
