Frequently Asked Questions
What is the molar mass of Lead(II) oxide?
The molar mass of Lead(II) oxide (PbO) is 223.199 g/mol. That is the sum of the standard atomic weights of all 2 atoms in one formula unit: 1 × 207.200 + 1 × 15.999 = 223.199.
What is the molecular weight of Lead(II) oxide?
223.199 — the same number as the molar mass, but as a dimensionless ratio rather than in g/mol. The two terms describe the same arithmetic, so a molecular weight of 223.20 and a molar mass of 223.20 g/mol are the same answer.
How many moles are in 100 g of Lead(II) oxide?
100 ÷ 223.199 = 0.4480 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Lead(II) oxide?
By mass, Lead(II) oxide is 92.83% lead, 7.17% oxygen. Each element's share is its total mass in the formula divided by 223.199.
How many atoms are in one formula unit of Lead(II) oxide?
2: 1 lead, 1 oxygen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Lead(II) oxide contains 2 × 6.022 × 10²³ atoms in total.
