QuestionCalculate the formula units in of lead(IV) oxide, .
Studdy Solution
STEP 1
Assumptions1. The mass of lead(IV) oxide given is500g. We know the chemical formula of lead(IV) oxide is
3. We need to find the number of formula units in this mass4. We use Avogadro's number () to convert moles to formula units5. The molar mass of lead(IV) oxide can be calculated using the atomic masses of lead (b,207. g/mol) and oxygen (,16.0 g/mol)
STEP 2
First, we need to calculate the molar mass of . The molar mass is the sum of the atomic masses of each atom in the formula.
STEP 3
Now, plug in the atomic masses of lead and oxygen to calculate the molar mass.
STEP 4
Calculate the molar mass of .
STEP 5
Now that we have the molar mass, we can calculate the number of moles in500g of . The number of moles is the mass divided by the molar mass.
STEP 6
Plug in the values for the mass and the molar mass to calculate the number of moles.
STEP 7
Calculate the number of moles in500g of .
STEP 8
Now that we have the number of moles, we can calculate the number of formula units. The number of formula units is the number of moles multiplied by Avogadro's number.
STEP 9
Plug in the values for the number of moles and Avogadro's number to calculate the number of formula units.
STEP 10
Calculate the number of formula units in500g of .
There are formula units in500g of lead(IV) oxide.
