4. The density of lead is 11.3 g/cm, Determine the mass of 4.25 cm of lead, (18.09)

48.03grams

Explanation:

Density of a substance is calculated as follows:

Density (g/cm³) = mass (g) / volume (cm³)

Based on the information given in this particular question:

Density of lead (Pb) = 11.3 g/cm³

Volume of lead (Pb) = 4.25 cm³

Density = m/V

11.3 = mass/4.25

Mass = 48.025

= 48.03grams.

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
