A)16.0 g
B)24.0 g
C)7.2 g
D)0.8 g

Question

Quizplus · Accepted Answer

The reaction between hydrofluoric acid (HF) and sodium hydroxide (NaOH) produces sodium fluoride (NaF) and water (H2O). According to the law of conservation of mass, the mass of the reactants equals the mass of the products. Given that 8.0 g of HF and 16.0 g of NaOH react to produce 16.8 g of NaF, the total initial mass is 8.0 g + 16.0 g = 24.0 g. Subtracting the mass of the NaF from the total mass gives the mass of water produced: 24.0 g - 16.8 g = 7.2 g.
