Final answer:
To find the volume of a 35g piece of zinc, divide the mass by the density of zinc (7.140 g/cm³), resulting in a volume of about 4.902 cm³.
Step-by-step explanation:
To calculate the volume of a piece of zinc with a mass of 35g, we need to use the formula for density, where density = mass/volume. We know from provided information that the density of zinc is 7.140 g/cm³. Using the density, we can rearrange the formula to find volume: volume = mass / density. So, we divide the mass of the zinc sample by its density to find its volume:
Volume = 35g / 7.140 g/cm³ = 4.902 cm³ (rounded to three decimal places)
Therefore, the volume of the zinc sample is approximately 4.902 cm³.
