Calculate the mass of the solution with a mass fraction of sodium hydroxide in it 23%, if 4.6 g of sodium hydroxide was used to prepare the solution.
Given:
w (NaOH) = 23% = 0.23
m in islands (NaOH) = 4.6 g
To find:
m solution (NaOH)
Decision:
m solution (NaOH) = m in-va / w = 4.6 g / 0.23 = 20 g
Answer: the mass of the solution is 20 g
