Homework Statement
say it says Al2S3(numbers are subscripts) is that saying you have 3 moles of sulfur?
The molecular formula for Al2S3 is aluminum sulfide.
The mole ratio for Al2S3 is 3 to 1, meaning that for every 3 moles of aluminum, there is 1 mole of sulfur.
The atomic mass of Al2S3 is 150.16 g/mol.
The mole ratio for a compound is determined by the coefficients in a balanced chemical equation. For example, the balanced equation for the reaction between aluminum and sulfur to form Al2S3 is 2Al + 3S → Al2S3. This means that the mole ratio of Al to S is 2:3.
The mole ratio is crucial in stoichiometry as it allows for the calculation of the amount of reactants needed or products formed in a chemical reaction. It also helps in determining the limiting reactant and the theoretical yield of a reaction.
