Solution:
Molar mass of 2-napthol = 144.17 g mol-1
Molar mass of 4-aminobenzenesulfonic acid = 173.2 g mol-1
Mass of 2-napthol in 0.0026 mol = number of moles x molar mass = 0.0026 mol x 144.17 g mol-1 = 0.3478 g
Mass of 4-aminobenzenesulfonic acid = number of moles x molar mass = 0.0026 mol x 173.2 g mol-1 = 0.4503 g
how many grams are in 0.0026 mol of 2-napthol+4-aminobenezesulfonic acid
