Molar mass of sodium bicarbonate = 84 g/mol
Moles of NaHCO3 in 1.5 g = 1.5/84 = 0.0178 mol
Molar mass of citric acid = 192.124 g/mol
Moles of citric acid in 1.5 g = 1.5/192.124 = 0.0078 mol
2 moles of sodium bicarbonate react with 1 mole of citric acid.
0.0178 mol of sodium bicarbonate reacts with 0.0178/2 = 0.0089 mol of citric acid
Available citric acid is only 0.0078 mol
0.0078 mol of citric acid reacts with 0.0078*2 = 0.0156 moles of sodium bicarbonate.
Excess sodium bicarbonate = 0.0178-0.0156 = 0.0022 mol
Mass of 0.0022 mol of NaHCO3 = 0.0022*84 = 0.1848 g
Answer : 0.1848 g
