You may want to reference (Page) Section 12.4 while completing this problem. Calculate the mass percent (m/m) for the solute in each of the following solutions. ▼ Express your answer using two significant figures. m/m = 11 % Submit Previous Answers Part C ✓ Correct Since the mass of H₂O is given rather than the total mass of the solution, you must add the mass of KOH given to find the total mass of the solution used in the denominator when calculating mass percent. Therefore, mass% = 41.0 g of Na2CO3 in 277.5 g of Na2CO3 solution Express your answer using two significant figures. Review | Constants I Periodic Table 3.9g KOH 3.9g KOH+333g H₂O x 100
