Answer #1

a) 2.12 g of proscaline / 239g/mol = 0.0088 mol

4.17g of AgI / 234.8 g/mol = 0.01776 mol

Moles of AgI is equivalent to moles of methoxyl groups due to the reactions that take place are all stoichiometrically equivalent.

Ratio is double, so proscaline has 2 methoxyl groups.

b) 1.06 g of mescaline / 211 g/mol = 0.005 moles

3.54 g of AgI / 234.8 g/mol = 0.015 moles

Ratio is triple, so mescaline has 3 methoxyl groups.
