Final answer:
To find the density of the screw, divide its mass (10 grams) by its volume (7 mL), yielding a density of 1.43 g/mL.
Step-by-step explanation:
The question asks for the calculation of the density of a screw given its mass and volume. Density is defined as mass per unit of volume which can be expressed as:
Density (g/mL) = Mass (g) / Volume (mL)
In the given problem, the screw has a mass of 10 grams and a volume of 7 mL. To find the density of the screw, we divide the mass by the volume:
10 grams / 7 mL = 1.43 g/mL
Therefore, the density of the screw is 1.43 g/mL.
