Answer:
(1) 0.10 (2) 17.8 g
Explanation:
Since the reaction ratio is 1:1, you will need to convert the provided masses into moles to get the results:
MW of anthracene = 178.23 g/mol
MW of maleic anhydride = 98.06 g/mol
a) mass of anthracene = 178 mg x 1 g/ 1000 mg = 0.178 g of anthracene
Moles of anthracene = 0.178 g of anthracene/ 178.23 g/mol
= 0.001 mol anthracene
0.001 mol anthracene x 1 mol of maleic acid/mol of anthracene
= 0.001 mol of maleic anhydride
mass of maleic anhydride = 0.001 mol x 98.06 g/mol = 0.10 g
b) moles of maleic anhydride = 9.8 g/ 98.06 g/mol = 0.099 moles
0.099 moles of maleic anhydride x 1 mol of anthracene/mol of maleic anhydride =
0.099 mol of anthracene
g of anthracene = 0.10 mol x 178 g/mol = 17.8 g
