"2.25% by weight" means 2.25 g of NaHCO₃ in 100 g of solution. To find out how much NaHCO₃ is in 150 g of solution, we can set up a proportion: 2.25 g NaHCO₃ / 100 g solution = x / 150 g solution Cross-multiplying gives: 100 g solution * x = 2.25 g NaHCO₃ * 150 g solution Simplifying: x = (2.25 g NaHCO₃ * 150 g solution) / 100 g solution = 3.38 g NaHCO₃ Therefore, the answer is B: 3.38 g.
