# Let's Discover the Formula of Lead Oxide!

## What is the formula for lead oxide (PO2)?

Given data: 207 g of lead combines with oxygen to form 239 g of lead oxide.

## Answer:

The formula for lead oxide (PO2) can be determined using the given information.

The formula for lead oxide (PO2) can be determined using the given information. The equation for the reaction is: Pb + O2 → PO2. From the equation, we can see that 207 g of lead combines with oxygen to form 239 g of the lead oxide. The molar mass of lead (Pb) is 207 g/mol, and the molar mass of oxygen (O2) is 32 g/mol. To find the formula of the lead oxide, we need to calculate the moles of lead and oxygen.

Moles = mass / molar mass. For lead, moles = 207 g / 207 g/mol = 1 mol. For oxygen, moles = (239 g - 207 g) / 32 g/mol = 1 mol. Therefore, the formula of the lead oxide (PO2) indicates that 1 mole of lead combines with 1 mole of oxygen to form lead oxide.
