Stoichiometry chemistry

Question

How many grams of NaOH will be needed to produce 1.045 x 10^23 molecules of NaC2H3O2?

Answer 1

1). Convert 1.045x10²³ molecules of NaC₂H₃O₂ to moles

2). Convert moles of NaC₂H₃O₂ to moles Na

3). Convert moles Na to moles NaOH

4). Convert moles NaOH to grams NaOH

1). 1.045x10²³ molecules NaC₂H₃O₂ x 1 mol/6.02x10²³ molecules = 0.174 moles NaC₂H₃O₂

2). 0.174 NaC₂H₃O₂ x 1 mol Na / mol NaC₂H₃O₂ = 0.174 mols Na

3). 0.174 mols Na x 1 mol NaOH / mol Na = 0.174 mols NaOH

4). 0.174 mols NaOH x 39.99 g NaOH/ mol NaOH = 6.94 g NaOH
