# Lead Oxide Formula Calculation

## What is the formula of lead oxide?

Is it:

a. Pb × 159

b. Pb × 0.0003

c. Pb × 0.7904

d. Pb × 0.2093

## Answer:

The formula of the lead oxide is PbO.

Explanation:

The formula of the lead oxide can be determined using the given information. The total mass of the lead oxide is 239 g, and the mass of lead is 207 g. The mass of oxygen can be calculated by subtracting the mass of lead from the total mass of the lead oxide:

Mass of oxygen = Total mass of lead oxide - Mass of lead = 239 g - 207 g = 32 g

Therefore, the formula of the lead oxide is PbO, as lead has a relative atomic mass of 207 and oxygen has a relative atomic mass of 16.
