Answer:
11.3 g/cc
Step-by-step explanation:
To determine the density of a 4 mL sample of lead, we need to divide its mass by its volume.
The mass of the sample is given as 45.2 g/mL, which means that the sample has a mass of 45.2 grams. The volume of the sample is given as 4 mL, which is equivalent to 4 cubic centimeters (cc).
We can use the formula for density, D = M/V, to calculate the density of the sample. Plugging in the values we have for mass (M) and volume (V), we get: D = 45.2 g / 4 cc = 11.3 g/cc.
Therefore, the density of the 4 mL sample of lead is 11.3 g/cc.
