How many grams of sodium bicarbonate are in 250 mL of 8.4% sodium bicarbonate?

Final answer: To find the number of grams of sodium bicarbonate in 250 mL of an 8.4% sodium bicarbonate solution, multiply the volume by the concentration. Explanation: To calculate the number of grams of sodium bicarbonate in 250 mL of an 8.4% sodium bicarbonate solution, you need to multiply the volume in mL by the concentration (in decimal form) and the density of the solution. First, convert the volume to L by dividing by 1000: 250 mL ÷ 1000 = 0.25 L Next, multiply the volume by the concentration: 0.25 L * 0.084 = 0.021 g Therefore, there are 0.021 grams of sodium bicarbonate in 250 mL of an 8.4% sodium bicarbonate solution.
