What are moles?
- The mole is a measure or the base unit for the amount of substance present in the given sample.
- The mole, symbol mol, is the SI unit of amount of substance.
How to find moles from gram?
Divide the mass of the substance in grams by its molecular weight.
Atomic mass of C = 12u, atomic mass of O = 16u
CO₂ = C + 2O
= 12 + 2(16)
= 44 g/mol
1 mole of CO₂ = 44 g/mol
(4.5g CO₂ / 1) x (1 mol CO₂ / 44g CO₂) x (1 mol C/1 mol CO₂)
= 0.1022 mol CO2
Hence, 0.1022 moles are there in 4.5g of CO2.
