If a piece of lead has a volume of 19
mL, what is its mass?

The mass of lead is 216.6 g.

Explanation:

Given data:

Volume of lead = 19 mL

Mass of lead = ?

Solution:

To solve this problem we will apply the density formula.

In literature density of lead is 11.4 g/mL.

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

Now we will put the values.

11.4 g/mL = m/ 19 mL

m =  11.4 g/mL×19 mL

m = 216.6 g

The mass of lead is 216.6 g.

the answer is barium and copper bromide
