What is the mass of a 7.91 cm3 peice of lead having a density of 11.34

Mass of lead = 89.7 g

Explanation:

Given data:

Volume of lead = 7.91 cm³

Density of lead = 11.34 g/cm³

Mass of lead =  ?

Solution:

Formula:

d = m/v

d = density

m = mass

v = volume

Now we will put the values in formula.

11.34 g/cm³ = m/7.91 cm³

m = 11.34 g/cm³ × 7.91 cm³

m = 89.7 g

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
