grames of sodium hydroxide [naoh] solution in
To determine the mass percent of sodium hydroxide in the solution, you need to calculate the mass of sodium hydroxide, and then divide it by the total mass of the solution (sodium hydroxide + water), and finally multiply by 100.
Step 1: Find the mass of sodium hydroxide:
Given that 8 grams of sodium hydroxide (NaOH) was dissolved, the mass of sodium hydroxide is 8 grams.
Step 2: Find the total mass of the solution:
Given that 50 grams of water (H2O) was used to dissolve the sodium hydroxide, the mass of the solution is 50 grams.
Step 3: Calculate the mass percentage:
Mass percent = (Mass of sodium hydroxide / Total mass of the solution) × 100
Mass percent = (8 grams / (8 grams + 50 grams)) × 100
Mass percent = (8 grams / 58 grams) × 100
Mass percent = 0.1379 × 100
Mass percent = 13.79%
Therefore, the mass percent of sodium hydroxide in the solution is approximately 13.79%.
