Final answer:
The volume of the lead sample is approximately 7.98 ml.
Step-by-step explanation:
The density of a substance is calculated by dividing its mass by its volume. In this case, the mass of the lead sample is given as 91 g and the density is 11.4 g/ml. To find the volume, we can rearrange the formula to solve for volume: Volume = Mass / Density. Plugging in the numbers, we get Volume = 91 g / 11.4 g/ml = 7.98 ml.
So, the volume of the lead sample is approximately 7.98 ml.
