Final answer:
The object's density is calculated by dividing its mass (12.74g) by the volume of water it displaces (2.86 mL), resulting in a density of 4.46 g/mL.
Step-by-step explanation:
To calculate the density of an object, you must first find the object's mass and volume. The mass is given as 12.74g. To find the volume displaced, subtract the initial reading of the graduated cylinder (22.3 mL) from the final reading (25.16 mL), which equals 2.86 mL (since 25.16 mL - 22.3 mL = 2.86 mL). Density is mass divided by volume, so the calculation is:
Density = Mass / Volume
= 12.74 g / 2.86 mL
= 4.46 g/mL (rounded to two decimal places)
Therefore, the object's density is 4.46 g/mL.
To calculate the density of an object, you need to divide its mass by its volume. In this case, the mass of the object is given as 12.74g. The volume can be found by subtracting the initial reading of the graduated cylinder (22.3 mL) from the final reading (25.16 mL), which gives a volume of 2.86 mL. To find the density, divide the mass by the volume:
Density = mass / volume
Density = 12.74g / 2.86 mL
The density of the object is approximately 4.46 g/mL.
